Hi Alexander,

You can find the recommendations regarding partition sizes in
"Allocating Disk Space" chapter of the FreeBSD Handbook

This means that your partition layout should be like this:

/       512M
swap   4096M (2x RAM)
/tmp    512M
/var   1024M
/usr    rest

/var's size depends, among other things, on how many logs you want to
keep there (where they live by default); since your machine will not be
a server, 512M should be ok. Please note that /var/db/, the default
place for info about ports installed, occupies roughly 200M or more.

/usr depends on how many applications you need to run. Please note
that /usr is also the default place where applications will be compiled
(inside /usr/ports) and where a lot of distfiles (sources) or
(precompiled) packages will be stored, so huge upgrades can take a lot
of place. [Some applications need ~500M (Firefox), ~1G (gcc42) or
several gigabytes (OpenOffice) to compile. Distfiles can use 1-3G,
depending on cleaning policy you choose.] Therefore, since you have 80G,
it's not a bad idea to use /usr for /home as well (i.e. to have /usr
only; home will be /usr/home, symlinked from /home). Otherwise, you can
easily encounter too much (wasted) or too little free space on /usr.

I've recently configured a laptop with the aforementioned partition
sizes (with smaller swap).

(Besides this, don't forget to read about the difference between
"dedicated" and "sliced" disks in the Handbook.)
