Re: bind mounts, chroots, and mismatching kernel with userland



Corrupted, as in /boot disappeared once and fsck reports heaps of
errors.  (fsck did not successfully find /boot that time, and only found
one initrd (out of 3), no kernels).

i don't have any error messages at the moment (because the disk becomes
read only), but i'll take a picture next time it happens.  is there any
way to record the fsck output to a text file if it's running from the
drive itself?

mount options:
/dev/sda1 on / type ext4
(rw,noatime,errors=remount-ro,user_xattr,barrier=1,data=ordered,discard)
tmpfs on /home/jayen/pkg/64/tmp type tmpfs
(rw,nosuid,nodev,relatime,size=814512k)
/dev/sda1 on /home/jayen/pkg/64/home type ext4
(rw,noatime,errors=remount-ro,user_xattr,barrier=1,data=ordered,discard)
proc on /home/jayen/pkg/64/proc type proc (rw,nosuid,nodev,noexec,relatime)
udev on /home/jayen/pkg/64/dev type devtmpfs
(rw,relatime,size=10240k,nr_inodes=213489,mode=755)
sysfs on /home/jayen/pkg/64/sys type sysfs (rw,nosuid,nodev,noexec,relatime)

fstab:
proc            /proc           proc    defaults        0       0
UUID=2b04563a-22b9-4b8a-b7c3-98774b749d7e /               ext4
errors=remount-ro,noatime,discard 0       1

/tmp    /home/jayen/pkg/64/tmp  bind    defaults,bind   0       0
/home   /home/jayen/pkg/64/home bind    defaults,bind   0       0
/proc   /home/jayen/pkg/64/proc bind    defaults,bind   0       0
/dev    /home/jayen/pkg/64/dev  bind    defaults,bind   0       0
/sys    /home/jayen/pkg/64/sys  bind    defaults,bind   0       0

Thanks,
Jayen
