I don't know if that is normal behavior or a bug, but you |
| 39 |
may be able to work around it by using "LABEL" in fstab |
| 40 |
instead of using sda, sdb, etc. |
| 41 |
|
| 42 |
I have |
| 43 |
LABEL=amd64 / ext3 noatime,nodiratime 0 1 |
| 44 |
|
| 45 |
instead of |
| 46 |
/dev/sdb5 / ext3 noatime,nodiratime 0 1 |
| 47 |
|
| 48 |
where I set the disk label with "e2label /dev/sdb5 amd64" |
| 49 |
and similar steps for the other disks. |
