I already regret making my root partition only 10Go. Between LaTeX and my dual 32/64-bits architecture (thanks videogames) I'm almost out of space.
@laeti Bind mounting? I never heard of that. I'll give it a look :).
@laeti Thank you for the explanation!
@Sylvhem it's basically mounting a directory in a mountpoint.
For example, you have /dev/sda3 mounted at /srv and a directory /srv/home
You can do mount -o bind /srv/home /home and you have the content of /srv/home in /home.
