Periodically I suffer from / being full. I feel mine is too large, however, I would be interested to see what size people 'generally' have in normal use. I would say I'm a typical 'ordinary' Desktop user - mainly email and web surfing although I occasionally do some video editing. I have always had a separate partition for / - at the moment I have a LVM environment with a specific LV for /. Additionally I have deleted snap from my system. Currently my / size is 22G which to me seems large compared to previous ubuntu installs.
Code:
dad@dadubuntu:~$ df -h

Be interested to see what / size people have on their machines.
