So I don't have to have the complete path in fstab like this: |
| 60 |
|
| 61 |
/dev/disk/by-label/boot /boot ext2 noatime 1 2 |
| 62 |
/dev/disk/by-label/root / reiserfs defaults 0 1 |
| 63 |
/dev/disk/by-label/swap none swap sw 0 0 |
| 64 |
/dev/disk/by-label/portage /usr/portage ext3 defaults 0 1 |
| 65 |
/dev/disk/by-label/home /home reiserfs defaults 1 1 |
| 66 |
|
| 67 |
Can you post a grub.conf file that uses labels? Sort of a example to |
| 68 |
look at and go by. |
