Much the same here, except that /var is on /, for reasons I explained
elsewhere, but /var/log is a dedicated partition. Likewise, I have
several partitions that hold data that would normally be part of /home, so
/home itself is smaller, 10 gig or so. My big partition is the
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
volume) is the one that contains my non-critical ccache, portage-tree, and
usrsrc/kernel stuff.
My fstab is /heavily/ commented, and includes all sorts of backup
partition entries, plus my old single PATA disk entries, but here it is:
