I'm not an LVM user so I live with my partitioning for years. I would opine that 10GiB is rather risky for a root partition (with /home separate). My smallest root partition, on an old laptop that I've been using since 2009, is 15GiB (74.5 GiB drive). I'm not a DE user, which might reduce usage a little, but /usr alone ranges from 8.4GiB (jessie on that laptop) to 10.2GiB (wheezy, as it happens, on a desktop). That's without giving any consideration to /var and /tmp. > >Should i make a different partition for /home/ ? > > I don't -- I put my bulk data on a file server, including all e-mail > attachments.

I would find that rather risky, so I have a "proper" separate, encrypted /home that ranges from 50GiB (laptop) to ~400GiB (desktops)—basically, the rest of the drive, though one laptop gives a fair amount of space over to a W10 installation. Bear in mind that were you to make your root far too large, it's easy enough to borrow some space by symlinking to, say, /var/local/myname (for unencrypted, less sensitive material). Cheers, David.
