Comment 22 for bug 431040

  I tried your debugging routine on a second try but could not find the logging output.
I don't know where it could have been written, as / was mounting read-only and not getting remounted.

Again I recovered from console 2, this time remounting / rw and then going straight to gdm(which worked and indeed sent me to my LUKS home directory), ignoring the garbage from df /home. df / home reported the tmpfs again-but with the CORRECT percentage used for the LUKS partition shown.

Here's what turned up in mtab:

/dev/sda1 / ext4 rw,relatime,errors=remount-ro 0 0
proc /proc proc rw 0 0
binfmt_misc /proc/sys/fs/binfmt_misc binfmt_misc rw,noexec,nosuid,nodev 0 0
none /sys sysfs rw,noexec,nosuid,nodev 0 0
udev /dev tmpfs rw,mode=0755 0 0
none /dev/pts devpts rw,noexec,nosuid,gid=5,mode=0620 0 0
none /dev/shm tmpfs rw,nosuid,nodev 0 0
none /var/run tmpfs rw,nosuid,mode=0755 0 0
none /var/lock tmpfs rw,noexec,nosuid,nodev 0 0
none /lib/init/rw tmpfs rw,nosuid,mode=0755 0 0
gvfs-fuse-daemon /home/luke/.gvfs fuse.gvfs-fuse-daemon rw 0 0
/dev/fuse /home/luke/.gvfs fuse rw,nosuid,nodev,user=luke 0 0
tmpfs /mnt/RAMDISK tmpfs rw,size=10% 0 0
/mnt/RAMDISK/.mozilla /home/luke/.mozilla none rw,bind 0 0

RAMDISK now belongs there, as it is now mounted for volatile(secure) web browsing, but mtab does not show /dev/mapper/vg0-home (mounted ANYWHERE), even though it is obviously mounted as I akm using it! This behavior is the exact opposite of the write but not mount behavior I got in the AMD while playing with the script. Again, I suspect some sort of context-sensitive bug in mount itself. If I get such problems with simple scripts, they will make unending trouble in debugging compiled binaries.

Mount needs to be fixed, then mountall can be fixed. Meanwhile, that fsck progress support should be added to the existing mountall code so it can be debugged in parallel to the mount bugs, given the tight schedule.

Since the changelog for mount doesn't show any likely causes, the underlying trouble has probably been there all along, just waiting for faster routines to trigger them.

Here's what's in fstab:

# /etc/fstab: static file system information.
#
# Use 'vol_id --uuid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
