On my PC and all my home servers I keep my root partition at 10GB and haven’t had any issues (although I keep everything that isn’t hardware related or a system utility in home).
On my PC I crammed arch, all of KDE (+extra KDE utilities), and some other system stuff like LACT and distrobox in the 10GB root partition and run almost everything else as a flatpak installed to home.
On my servers I do the same thing but all my services are in podman containers in /opt.
Having all the software needed to make the machine work be isolated from my custom home junk makes me feel better, and I like that I can mount root as read-only to make it immutable



Hey I know it’s been months, but after the discussion in this thread I built a new computer with a real GPU (I went AMD and I’m using the MESA drivers) and tons of ram, and I am happily running LibreWolf and it’s awesome!
In terms of ram utilization and GPU acceleration on this new machine with modern hardware, Firefox is negligible, as everyone told me it would be!
