I keep /usr mounted read-only, and I remount it read-write before I
install a new package. (OK, I remount it read-write _after_ dpkg
fails the first time.) Nearly anything writing there is a bug.
There a two things I know of:
/usr/src/linux needs to be rw. /usr/src should be a different
partition or, like I have here, a symlink to /var/src (or /home/src).
XFree86 3.3-3 has a bug where it needs to write to
/usr/X11R6/lib/X11/xkb/compiled. This is symlinked to
../../../../../var/lib/xkb here as a temprorary measure.
