| 02:06.17 | Pali | merlin1991: on tmo there are more people which want ext4 on MyDocs and also on home |
| 02:06.43 | Pali | I looked into script where are hardcoded vfat and ext3 strings |
| 02:07.34 | Pali | and scripts working: MyDocs is first partition which has 'c' id in MBR table on /dev/mmcblk0 |
| 02:08.16 | Pali | home is partition on /dev/mmcblk0 which has in MBR table '83' id |
| 02:08.32 | Pali | (first partition) |
| 02:09.09 | Pali | so both /home and MyDocs are not hardcoded to partition number but to id in MBR table |
| 02:11.07 | Pali | problem is that there is convention (and parition programs using it) that 'c' id means FAT32 partition, 83 is some linux partition (ext*) |
| 02:11.52 | Pali | kerio, freemangodon, merlin1991, DocScrutinizer05: if you have idea how to fix that, ping me |
| 02:12.36 | Pali | solution is not easy, because more people swapped MyDocs and home partition numbers |
| 02:13.44 | Pali | we need to determinate which partition is mydocs, home and swap and then generate proper /etc/fstab with correct filesystem type |
| 02:18.42 | DocScrutinizer05 | Pali: well, the solution is rather simple, though radical. Get proper persistent fstab |
| 02:19.55 | DocScrutinizer05 | tbh I still don't get the rationale yet of generating a fake fstab on each boot |
| 02:21.59 | Pali | DocScrutinizer05, ok, how to generate fstab? |
| 02:22.05 | Pali | see above problems ^^^ |
| 02:22.29 | Pali | we can break devices when we switch home & mydocs & swap |
| 02:23.03 | Pali | determinating which partition is swap could be easy |
| 02:23.18 | Pali | but how to determinate which partition is /home and which MyDocs? |
| 02:24.33 | DocScrutinizer05 | well, somebody must have changed that, or it will be as we're used to. The one who changes fs type also has to ccreate the fstap for that |
| 02:24.40 | DocScrutinizer05 | fstab* |
| 02:25.11 | Pali | yes, but now maemo scripts generating it |
| 02:25.45 | Pali | so I really do not know if some script is not going to remove fstab |
| 02:25.50 | DocScrutinizer05 | yes, and if we want to fix it, we need to change that to using a static fstab |
| 02:26.31 | Pali | maybe another question: do we need fstab? |
| 02:26.41 | DocScrutinizer05 | sure |
| 02:26.51 | Pali | mounting mmc card & usb disks in host mode are mounted automatically by ke-recv |
| 02:26.59 | Pali | which ignoring fstab |
| 02:27.11 | Pali | and calling directly mount device mount_point |
| 02:27.18 | Pali | same is for MyDocs |
| 02:27.23 | DocScrutinizer05 | one more reason why no dynamic fstab is needed |
| 02:27.46 | Pali | in fstab is only home & MyDocs |
| 02:27.55 | Pali | and swap |
| 02:28.02 | DocScrutinizer05 | I really don't understand why all this is the way it is |
| 02:28.28 | Pali | changing ke-recv is not simple |
| 02:28.48 | Pali | so I think that mount code in ke-recv is not going to be changed |
| 02:28.49 | DocScrutinizer05 | but feasible |
| 02:29.23 | Pali | and there is problem that all maemo apps want sd card in /media/mmc1 |
| 02:29.36 | Pali | and usb disks in /media/usb/sd* |
| 02:30.13 | Pali | so fstab for SD card & usb disks is useless |
| 02:30.36 | Pali | and also when I create new partition on SD card I really do not want to edit fstab for mounting SD card |
| 02:31.07 | Pali | linuxes on desktop also doing autodetection of external usb disks and SD cards |

| 09:08.50 | kerio | ohai Pali |
| 09:09.08 | kerio | you missed my monologue regarding fstab :) |
| 09:09.25 | Pali | hi |
| 09:10.40 | Pali | kerio, we can use blkid or hal which tell us filesystem on mmc block device |
| 09:10.53 | Pali | so hardcocded ext3/vfat can be fixed with blkid |
| 09:11.02 | Pali | everywhere |
| 09:11.27 | kerio | Pali: that doesn't involve having a real fstab |
| 09:11.41 | Pali | but you can see that genfstab.awk reading MBR parittion id |
| 09:12.27 | Pali | I think that good solution would be: add new config file with GENFSTAB= option |
| 09:12.33 | Pali | which user can change |
| 09:13.20 | Pali | kerio, but first we should solve how to determinate which partition is /home and which MyDocs |
| 09:13.37 | kerio | what do you mean "determine"? |
| 09:14.08 | Pali | which partition should be mounted to /home? |
| 09:14.14 | Pali | and which to MyDocs? |
| 09:14.14 | kerio | /dev/mmcblk0p2 |
| 09:14.21 | Pali | why? |
| 09:14.21 | kerio | /dev/mmcblk0p1 |
| 09:14.24 | kerio | actually no, even better |
| 09:14.28 | kerio | the partitions specified in /etc/fstab |
| 09:14.38 | Pali | some people swapped p2 and p1 |
| 09:14.47 | kerio | well those people should fix their fstab |
| 09:14.55 | Pali | and because genfstab.awk reading MBR id, it generate correct fstab |
| 09:15.07 | kerio | good, so the fstab is already correct |
| 09:18.02 | Pali | kerio, there is another problem: yesterday I booted 3.8 kernel on maemo5, and udev did not changed mmc0 and mmc1, so I had mmc1 for eMMC |
| 09:18.21 | Pali | without fixing rcS-late I was not able to boot 3.8 kernel |
| 09:18.33 | kerio | Pali: does our "mount" understand UUIDs? |
| 09:18.47 | Pali | so I think that static fstab is not good solution for booting more kernels |
| 09:18.57 | kerio | it is |
| 09:19.05 | kerio | mount by UUID |
| 09:19.11 | Pali | UUID sounds like good idea, but |
| 09:19.25 | kerio | and if you're going to boot 3.8 then you're outside of the realm of the normal user |
| 09:19.32 | Pali | reformating MyDocs on windows will change fat uuid |
| 09:19.50 | Pali | kerio, I want easy solution for booting upstream kernel |
| 09:19.59 | Pali | and not changing tons of config before reboot |
| 09:20.05 | kerio | and i want a pony |
| 09:20.30 | kerio | fremantle has unspoken assumptions regarding the partition layout of /dev/mmcblk* |
| 09:20.32 | Pali | it is not normal to change configs if you are going to boot another kernel |
| 09:20.56 | kerio | but it's normal to change configs if you're going to swap hardware around |
| 09:21.00 | kerio | which is what's effectively happening |
| 09:21.05 | Pali | kerio, for some reason ke-recv correctly detected which mmc device is SD card |
| 09:21.09 | Pali | and mounted it correctly |
| 09:21.37 | Pali | it mounted /dev/mmcblk0p1 to /media/mmc1 |
| 09:22.13 | Pali | so seems that SD card is not hardcoded for /dev/mmcblk1* |
| 09:23.36 | kerio | yeah, the sd card can be automounted by ke-recv |
| 09:24.06 | kerio | (i'd still like a bit more documentation on how to trigger that manually, but whatever) |
| 09:24.16 | kerio | /home is mounted during rcS-late |
| 09:24.21 | Pali | yes |
| 09:25.14 | kerio | and the UUID of /home doesn't change |
| 09:25.22 | kerio | well |
| 09:25.32 | kerio | hrmpf |
| 09:25.46 | Pali | kerio, can we check if mc block device has root folder "user" before mouting? |
| 09:25.50 | Pali | *mmc |
| 09:26.03 | Pali | because in /home should be "user" |
| 09:26.03 | kerio | we could mount and unmount if we're wrong, but that's bullshit |
| 09:26.11 | kerio | "mkdir user" |
| 09:26.35 | Pali | no, I mean that device which has "user" is /home |
| 09:26.41 | kerio | yep, that's bullshit |
| 09:27.05 | kerio | i could have multiple extfs partitions with a "user" directory |
| 09:27.49 | Pali | now first partition with id '83' is mounted to /home |
| 09:28.05 | kerio | in the correct device |
| 09:28.17 | kerio | because of the HAL renaming |
| 09:28.24 | Pali | udev doing renaming |
| 09:28.30 | kerio | right, udev |
| 09:28.35 | Pali | and rcS-late has hardcoded mmc0 |
| 09:28.40 | kerio | well, make your 3.8 kernel's udev rename them too |
| 09:29.02 | Pali | kerio, problem is that I do not know why that renaming udev rule not working |
| 09:29.11 | Pali | I tried to check out why |
| 09:29.18 | Pali | but I think that rule should work |
| 09:29.28 | kerio | Pali: /dev/mmcblk0 being the eMMC and /dev/mmcblk1 being the uSD is an unwritten assumption in fremantle/n900 anyway |
| 09:29.46 | Pali | kerio, yes, but this can be also easy fixed |
| 09:30.12 | Pali | in /sys there is item which tell us if mmc device is interal or external |
| 09:30.18 | kerio | i mean an assumption in every piece of (related to partitions) software |
| 09:30.24 | Pali | script /bootmenu.sh doing it |
| 09:31.48 | kerio | Pali: holy shit, our "mount" understands LABEL= |
| 09:32.11 | Pali | I'm for this: Add option for user to stop generating fstab, but also fix autogenerating to support any filesystem |
| 09:33.19 | Pali | btw is swapon reading swap partitions from /etc/fstab? |
| 09:33.27 | kerio | yeah, rcS-late just does a swapon -a |
| 09:33.38 | kerio | after it's generated |
| 09:33.41 | Pali | if yes, this can solve also problem with adding more swaps |
| 09:34.18 | kerio | i have, around the block of code that generates fstab: |
| 09:34.23 | kerio | <PROTECTED> |
| 09:34.58 | kerio | but that can be changed to be something like if [ ! -e /etc/default/nogenfstab ]; then |
| 09:35.00 | kerio | or something like that |
| 09:36.42 | Pali | kerio, it will be very bad if we hardcode that first partition will be mounted to MyDocs (any supported filesystem by kernel) and second will be /home? |
| 09:37.22 | kerio | Pali: linux doesn't care much about the partition type |
| 09:37.23 | Pali | because I do not see any good solution how to generate fstab with MyDocs and home with any supported filesyetem |
| 09:37.40 | kerio | MyDocs and mmc things are still handled by ke-recv |
| 09:37.51 | kerio | MyDocs is the first partition with id 0c in the internal memory |
| 09:37.57 | kerio | regardless of the actual file system |
| 09:38.01 | kerio | (kinda ugly, but meh) |
| 09:38.13 | Pali | kerio, yes this is reason why I do not like to see using MBR ids |
| 09:39.47 | Pali | ok, so I will try to change all maemo scripts to, respect some nongenfstab settings and generation will always use p1 for MyDocs and p2 for /home (with autodetection of filesystem) |
| 09:40.08 | kerio | Pali: what's wrong with having a fixed partition order, anyway? |
| 09:40.31 | Pali | users which already using switched partitions |
| 09:40.41 | kerio | Pali: they won't need to move data around |
| 09:40.48 | Pali | becase maemo system has support for that |
| 09:40.50 | kerio | you can just change the partition order |
| 09:41.10 | Pali | kerio, yes it is possible :-) |
| 09:41.25 | kerio | fdisk will yell at you, but he'll do it |
| 09:41.32 | Pali | but I think that (s)fdisk has no command for reordering partition |
| 09:41.51 | kerio | Pali: whatever, change the ordering in some way |
| 09:42.05 | kerio | delete the partitions and recreate them in the opposite order with the exact same start/end |
| 09:42.12 | Pali | yes |
| 09:42.12 | kerio | (but swapped) |
| 09:42.33 | Pali | also u-boot has hardcoded first emmc partittion for bootmenu |
| 09:42.39 | kerio | we should facilitate users who wish to customize their system like that, but we and they can't hope that everything will happen automagically |
| 09:42.50 | Pali | I will try to remove hardcoded fat32 option |
| 09:43.08 | kerio | Pali: so you're going to outright ignore the mbr partition type? |
| 09:43.32 | kerio | Pali: also, how does the autodetect work? |
| 09:43.41 | Pali | I do not see better solution... |
| 09:43.43 | kerio | ext3 can be safely mounted as ext4 and then back |
| 09:43.52 | kerio | but ext4 with extents won't be mountable as ext3 |
| 09:43.55 | Pali | kerio, autodetect will read some bytes from partittion and detect type |
| 09:44.04 | kerio | although the ext* status in the kernel is always weird like that |
| 09:44.12 | kerio | and it's the same code anyway, right? |
| 09:44.23 | Pali | run sudo blkid and will show all info |

| 09:53.33 | kerio | and by we i obviously mean you :P |
| 09:53.59 | Pali | and how? |
| 09:54.00 | kerio | Pali: how about a setting to "prefer single partition" in the export of the uSD |
| 09:54.13 | kerio | if there's that setting, and there's a partition table, you export the first partition |
| 09:54.26 | Pali | ok |
| 09:54.51 | kerio | you need to check if there's a partition table, because uSDs can also be superfloppys with no partition table and the filesystem on the whole device |
| 09:55.19 | kerio | Pali: make it threefold: export whole device (default), export single partition, no export |
| 09:55.23 | kerio | with no export, you only export mydocs |
| 09:58.48 | kerio | Pali: also, my sd is mounted in /media/mmc1, not /media/mmc1p1 |
| 09:59.59 | Pali | kerio, yes, because one partition must be mounted to /media/mmc1 |
| 10:00.11 | kerio | i see |
| 10:00.20 | Pali | because camera (or another application, maybe modest) had hardcoded that path |
| 10:00.34 | Pali | and ke-recv mounting first fat partition for /media/mmc1 |

| 10:06.47 | Pali | I do not know |
| 10:06.55 | Pali | what is hardcoded in ke-recv |
| 10:07.15 | kerio | anyway, i think that the invariant of the first partition must be somewhat preserved |

| 17:43.14 | kerio | i'm fairly sure that the whole point of exporting the whole sd is to deal with superfloppies |

| 18:20.05 | kerio | hm |
| 18:20.11 | kerio | why? :( |

| 18:20.56 | kerio | and most fscks |

| 18:26.19 | kerio | Pali: instead of figuring out device and type, use fsck |

| 18:26.35 | Pali | I used it |

| 18:27.50 | kerio | it's **the same binary** |

| 18:30.29 | kerio | /sbin/e2fsck, /sbin/fsck.ext3 and /sbin/fsck.ext4 have the same md5sum |
| 18:30.38 | kerio | how do i check if they're hardlinked to the same file? |
| 18:31.20 | kerio | Pali: they're the same binary, it just has different argument parsing |
| 18:31.41 | Pali | kerio, use stat |
| 18:31.46 | Pali | and check inode number |
| 18:32.08 | kerio | anyway, there's no way to specify the "version" of ext* to e2fsck |

| 19:03.50 | kerio | Pali: btw, you're forgetting to not call mount_home if /home is not on a separate partition in that version of rcS-late you pastebinned |
| 19:05.04 | Pali | yes, mount_home should not do anything if /home missing in etc/fstab |

| 19:06.12 | kerio | because if root_is_ubifs then we want a /home |
| 19:06.17 | kerio | we *need* a /home |

| 19:50.22 | kerio | DocScrutinizer05: remove the "hail mary" fsck -y that will probably do more bad than good in mount_home? |
| 19:51.00 | DocScrutinizer05 | eh? |
| 19:52.58 | kerio | pali is revolutioning the fstab thing, i'm helping a bit |
| 19:53.31 | kerio | in rcS-preinit, the part that mounts /home tries to mount, and if it fails to do so it runs a fsck -y on it |
| 19:54.06 | kerio | and i'm not sure if we actually want to ever risk running "fsck -y" on *anything* |
| 19:55.05 | kerio | Pali's modifications will allow the user to configure whether or not to run a fsck -a (automatic but only "safe" options) on home before mounting |
| 19:55.14 | kerio | which is much, much better |
| 19:55.41 | kerio | should we also keep the code that runs the POTENTIALLY DESTRUCTIVE AND COULD DO A LOT MORE DAMAGE fsck? |

| 20:12.20 | kerio | hm, what's the decision process for something like this? |
| 20:13.15 | kerio | DocScrutinizer05: let's put it this way: if fsck -a couldn't preemptively fix it, i very much doubt that fsck -y can, and before trying, you really, really, really want a backup |
| 20:13.20 | DocScrutinizer05 | pretty simple, if system can't boot there is no option |
| 20:13.37 | DocScrutinizer05 | ack for backup |
| 20:13.49 | DocScrutinizer05 | also ack for giving user a choice |
| 20:14.05 | kerio | DocScrutinizer05: "shit be fucked up, yo - you might want to do $foo, $bar and/or $baz to fix it. The system can't boot, push the power button to shut down" |
| 20:14.12 | DocScrutinizer05 | and also ack for fsck -a rather than -y |
| 20:14.20 | kerio | DocScrutinizer05: no, the preening will happen *before* the mounting |
| 20:14.39 | kerio | (and takes very little to no time, on a clean journaled system) |
| 20:14.56 | kerio | thus, it's not very useful to *redo* it |
| 20:21.45 | DocScrutinizer05 | when /home can't get mounted in a way that forbids system to boot up, we want to do something about it. We also want to do something about /home being mounted r/o *before* we can't umount it any more |
| 20:22.34 | kerio | DocScrutinizer05: yeah but stopping and saying "nope" is a much better option than blindly going ahead with a fsck -y |
| 20:22.39 | kerio | for the user's data |
| 20:22.58 | DocScrutinizer05 | so you could check if e.g. BM is installed, and if it is, boot up with /home r/o and display a suggestion to use BM to fix it |
| 20:24.12 | DocScrutinizer05 | if however no such alternative exists, you as well can go try and fix it right away, since there's no other option for the joe average user |
| 20:25.27 | kerio | sure there is! |
| 20:25.29 | kerio | #maemo! |
| 20:25.29 | kerio | :3 |
| 20:25.34 | DocScrutinizer05 | or you set a flag file on NAND/root that tells "home-been-mounted-r/o" and if on next boot it's again running into this error, you go fsck |
| 20:30.51 | kerio | besides, checking /proc/mounts is probably the result of cargo computing |
| 20:31.28 | kerio | you can check the return value |
| 20:33.46 | kerio | although to be fair i don't know if it has a different return value if "corrupted fs, mounted read-only" happens |

| 20:38.37 | kerio | Pali: hm, what does the "check" option do, when mounting ext*? |
| 20:39.05 | Pali | which check option? |
| 20:39.11 | kerio | "check" :) |
| 20:39.31 | kerio | no, wait |
| 20:39.44 | kerio | ...why are the only valid possibilities "none" and "nocheck"? :s |
| 20:41.11 | kerio | nevermind :) |
