I have / and /usr [sometimes one partition] mounted read-only on many
of my systems.  I like the peace of mind of KNOWING nothing'll go
wonky on 'em on a crash, I like the shorter fsck times, I kinda like
knowing there's that extra (very thin, but still extant) layer of
protection against a lot of automated attacks...  And, darnit, it just
feels cleaner.  I tend to have separate /var, /tmp, /home, and
/usr/local which are kept rw since they have live and
constantly-fiddled data on them, but everything else generally ends up
ro since I only need to write them at specific discrete times.  Out of
the 11 partitions (multiple disks) on my workstation, only those 4 are
generally rw.
