Again, so you don’t plan on installing anything extra or downloading stuff off the web? Lol.
I tried running arch in about 115GB of space, it wasn’t too bad but I had my /home directory on a separate drive. There’s no way I could get away with my OS+Home Directories on something as laughably small as that, unless I was just testing for a few weeks.
What’s the point then? Just to try each one for a few weeks to pick the one you like the most? In that case, it makes sense
