I don't, actually. I'm reacting to warnings of limited space received when upgrading Jessie. And previously when upgrading from Wheezy IIRC. > >>>> Device Boot Start End Sectors Size Id Type >>>> /dev/sda1 * 2048 19531775 19529728 9.3G 83 Linux >>>> /dev/sda2 19533822 312580095 293046274 139.8G 5 Extended >>>> /dev/sda5 19533824 27578367 8044544 3.9G 82 Linux swap / >>>> Solaris >>>> /dev/sda6 27580416 312580095 284999680 135.9G 83 Linux >>>> >>>> $ cat /etc/fstab >>>> # / was on /dev/sda1 during installation >>>> # /home was on /dev/sda6 during installation >>>> # swap was on /dev/sda5 during installation > > >>>> This must be a FAQ.

With /var taking less than 1 gb and /var/cache/apt/archives less than 1mb, /usr had seemed the elephant in the room. Might that be a way to go? I just need to get to Stretch for now. Thank you.
