I've lost everything and I don't know how to get it back. How can I repair my system all I have is a usb with slax linux. I am freaking out because I had a lot of projects on their that I hadn't pushed to github as well as my configs and rice. Is there any way to repair my system? Can I get a shell from systemd?
I don't know about you, but I tend to make lots of little changes to my setup all the time. Versioning makes it easy to roll back those individual changes, and to tell which change broke what. Sure, you could accomplish the same thing with backups, but versioning offers additional information with negligible cost.
Why not stick them in a git repo?
Because the benefit gets lost if there are lots of autogenerated config files. Someone else said 'stick only the files you write yourself in the repo' and I guess that's a better idea than to stick all of them in a repo.
