Hello.
Under /dev/disk, we find links that point to the devices
which host a filesystem. For example, suppose there's
a filesystem with the label Home and it's stored on
the LV called Home on the sys VG (ie. /dev/sys/Home).
We then find:
--($:~)-- ls -la /dev/disk/by-label/Home
lrwxrwxrwx 1 root root 21 15. Jun 2007 /dev/disk/by-label/Home -
../../mapper/sys-Home
Same for by-uuid, by-id and by-path (well, by-path is a
bit different, but please disregard that for this question).
Eg.:
--($:~)-- ls -la /dev/disk/by-uuid/73780e0c-0e0b-4afb-8412-77efc2ad8222
/dev/disk/by-id/dm-name-sys-Home
lrwxrwxrwx 1 root root 21 15. Jun 2007 /dev/disk/by-id/dm-name-sys-Home -
../../mapper/sys-Home
lrwxrwxrwx 1 root root 21 15. Jun 2007
/dev/disk/by-uuid/73780e0c-0e0b-4afb-8412-77efc2ad8222 - ../../mapper/sys-Home
What system is creating those symlinks during boot?
Who is responsible for doing that? Is it udev? Or something
from util-linux?
Reason for this question: Plain old curiosity :) I see that
this works very well on Gentoo but doesn't work on other
distributions...
Best regards,
Alexander Skwar
