The system is in use by ~50 people, and this has proven to be an alright setup
for it. What do you intend to use /opt for? I know this may be blasphemy, but
I've never been a big fan of /opt, I much prefer /usr/local. Do you intend to
install a lot of software? I assume this is for a desktop running X rather
then a server? I would definetly shrink /var and / I would remove /etc all
together, its a bad idea to have it seperated from /.
So ~50meg for / ~300 for /usr/openwin and no /etc partition. That saves you
550megs right there. If you get rid of opt(which I reccomend) you save another
2gigs. How large is your swap section? Do you intend to use your system as an
email or news server? If not shrink /var a LOT. /usr is probably about on target.
