the automatic disk allocation doesnt take ports developement into
account.

Well, from experience, /usr/ports itself doesnt matter much, but:
- /usr/obj/ports (or ${PORTSDIR}/pobj the default, which i never
personally used) needs sizing depending on what you build (a full build
of firefox with debug symbols takes ~10G iirc, probably same for webkit
and more for chromium)
- /usr/ports/distfiles needs sizing depending on what you build too
(350Mb per mozilla distfile), and needs pruning from time to time (i
tend to prune /usr/ports/mozilla which often gets gigabyte-sized with
many beta tarballs)
- /usr/ports/packages also needs sizing depending on what you build and
if you build stuff with debug syms. Also needs pruning from time to
time (and dont forget to prune under packages/${arch}/*, not only
packages/${arch}/all, otherwise you dont regain disk space)
afte after that, maybe only /usr/ports/plist tend to accumulate files
over time, but that's only text files.
if you want to run bulks, at least 100Gb for both packages and distfiles
is required.
/dev/sd0e 149G 88.9G 52.5G63%/usr/ports
68.1G /usr/ports/distfiles
is what i have on an old cluster bulk builder that i havent updated nor
cleaned in a while.
on my build vm that i use daily (mostly for mozilla builds but other
stuff too) i have ports under /home, and the given disk usage:
/dev/sd0i 27.3G 24.6G1.3G95%/home
/dev/sd0h 29.5G5.5G 22.6G20%/usr/obj
/usr/obj/ports/.ccache is limited to 8G, and im often limited by
distfiles or packages or objdir being full, but i tend to let old
distfiles and packages accumulate.
For a new machine where disk space doesnt matter much, i'd say
a 100Gb /usr/ports is comfortable. separate objdir can be helpful if
disk can be slow and its faster to newfs rather than rm'ing files.
