This will give me the following partitions:
/ 100MB, mirrored
/boot 80MB, mirrored
/usr, /var, et. All on ~12G RAID-5 array.
Does this look feasible? Can you see any major gotchas? Any better
suggestions?
How about:
Partition | sda | sdb | sdc | sdd |
----------+--------------+--------------+----------+----------+
1 | RAID-1 | RAID-1 | swap | swap |
| (/boot, 80M) | (/boot, 80M) | (130M) | (130M) |

This will give me the following partitions:
/boot 80MB, mirrored
/, /usr, /var, et. All on ~12G RAID-5 array.
360M swap spread across all 4 spindles
Adjust the capacities to suit.
Alternatively, use the other two spindles "next to" the /boot RAID-1
partitions to provide a RAID-1 or RAID-0 /tmp filesystem. However, I'd be
inclined to increase the swap area and use tmpfs (which is virtual-memory
based; i.e. RAM+swap) for /tmp.
