Resizing / on encrypted system [debian jessie, ext4, lvm(?)]
Ok, so I have no space left but plenty in /home. I would like to enlarge root somewhat.
I have googled on this problem and found some solutions but I'm a bit scared to try them out because when I installed jessie I choose to encrypt my system, I'm worrying if this might mess things up. Also I don't know if I have LVM or not.
What is the best way to do this in my particular situation?
Some information:
