You have /var and/or /tmp on separate filesystems? If not, that is
where things are being written to. Specificly, look in /tmp,
/var/log/, and under /var/spool. Is /var/tmp separate from /tmp? What
about /usr/tmp? If you don't run the machine 24/7, logrotate might not
be run, this would mean your log files (under /var/log) will grow and
grow and grow ... If you don't have an email alias for root (I assume
you don't login as root!), then /var/spool/mail/root will grow and grow
and grow ... as well (all sorts of silly messages sent to root). It is
also possible that stuff is accumulating under /var/spool/lpd as well,
although this will be small files.
