Hi! I’m using HP Pavillion Gaming 15 laptop with 256Gb SSD. I have installed NixOS 20.03 to this drive and gave it 25Gb as I always did with Debian before.
/home is the other partition so I had 25Gb for system only. But after 3 month of great experience it turns out that I can’t
nixos-rebuild switch because I have not enough space. I did
nix-collect-garbage -d and
/ is using 80% of storage for now and can’t rebuild.
After googling the topic I concluded that there is no way to widen
/nix/store space by mounting another partition somehow. Also I don’t want to use another computer to build my system. So I decided to reinstall NixOS properly this time.
The question is how much storage should I give to the system? I mean how large can system grow during the rebuild? From big software I use only Plasma, Firefox, VSCode and LibreOffice. But what if I decide to install CLion? What amount of storage can make me sure it’s enough to rebuild pure system?
Is it relevant to separate
/home when you have only 256Gb of space with NixOS?
