With regard to /opt, my SuSE handbook gives some advice, which I will paraphrase here:
the /opt partition is used by some (mostly commercial) programs to store their data.
It is then recommended to make a partition /opt, or to make your root partition big
enough to accommodate it. Some info is also given on disk usage in /opt by various
packages (all figures in Mb):
Cyberscheduler Software 30
Cygnus Source Navigator 20
Oracle 8 400
These are presumably the packages in SuSE using /opt (Although I notice that Acrobat
is not mentioned). Anyway, the total is 2173 Mb, but you are unlikely to use all of
these packages. 4Gb seems excessive, 2 would probably be more than sufficient.
Hope this info helps some
