Much the same here, except that /var is on /, for reasons I explained |
| 25 |
elsewhere, but /var/log is a dedicated partition. Likewise, I have |
| 26 |
several partitions that hold data that would normally be part of /home, so |
| 27 |
/home itself is smaller, 10 gig or so. My big partition is the |
| 28 |
multi-media partition, with data that would ordinarily be on /home. |

Stryper (yes, I'm a fan of the band, it's my generic RAID-0 striped |
| 56 |
volume) is the one that contains my non-critical ccache, portage-tree, and |
| 57 |
usrsrc/kernel stuff. |
| 58 |
|
| 59 |
My fstab is /heavily/ commented, and includes all sorts of backup |
| 60 |
partition entries, plus my old single PATA disk entries, but here it is: |
