You can also use container within NixOS and AFAICT even declare the containers which should be running. Also NixOS is sad to be stable, or am I missing something?
I am running Ubuntu server and I am… satisfied with it. It does what it should, no problems, nothing to worry about, stable AF (as any mature distro?). But lately I am thinking about switching to fedora server (I need to reset my system one way or another, because my space on the hard drive for the system ran out of space (it was a small drive)). I am using fedora on my work machine and I really like it, so I thought I could give fedora on my server a try.
Do you mean they are too frequent, or what do you mean?
