i have a similar solution with a raid5 for /opt /usr /home, etc. and a |
15 |
small / on raid1. but i think grub is better in this situation, because |
16 |
with the grub shell, in case of a failed disk, the changed |

identification of the subsequent disks can easily be corrected. i don´t |
18 |
know how lilo handles this. |
