I'm new to Trisquel myself, I have only a / partition of 20 GB and a /home
partition of about 108 GB plus about a 4 GB swap, about as simple as it can
be done. I have installed apache2 web server, mariaDB database server and a
few smaller packages and I have filled 6.5 GB on the 20 GB / partition. You
can use your /home partition when you install another OS, just tell the
partition manager to mount it as /home (don't format). That could save some
room for the future.
