Hello. |
| 2 |
|
| 3 |
Under /dev/disk, we find links that point to the devices |
| 4 |
which "host" a filesystem. For example, suppose there's |
| 5 |
a filesystem with the label "Home" and it's stored on |
| 6 |
the LV called "Home" on the "sys" VG (ie. /dev/sys/Home). |
| 7 |
We then find: |
| 8 |
|
| 9 |
--($:~)-- ls -la /dev/disk/by-label/Home |
| 10 |
lrwxrwxrwx 1 root root 21 15. Jun 2007 /dev/disk/by-label/Home -> ../../mapper/sys-Home |
| 11 |
|
| 12 |
Same for by-uuid, by-id and by-path (well, by-path is a |
| 13 |
bit different, but please disregard that for this question). |
| 14 |
Eg.: |
| 15 |
|
| 16 |
--($:~)-- ls -la /dev/disk/by-uuid/73780e0c-0e0b-4afb-8412-77efc2ad8222 /dev/disk/by-id/dm-name-sys-Home |
| 17 |
lrwxrwxrwx 1 root root 21 15. Jun 2007 /dev/disk/by-id/dm-name-sys-Home -> ../../mapper/sys-Home |
| 18 |
lrwxrwxrwx 1 root root 21 15. Jun 2007 /dev/disk/by-uuid/73780e0c-0e0b-4afb-8412-77efc2ad8222 -> ../../mapper/sys-Home |

|
| 20 |
What "system" is creating those symlinks during boot? |
| 21 |
Who is responsible for doing that? Is it udev? Or something |
| 22 |
from util-linux? |
| 23 |
|
| 24 |
Reason for this question: Plain old curiosity :) I see that |
| 25 |
this works very well on Gentoo but doesn't work on other |
| 26 |
distributions... |
| 27 |

Best regards, |
