what i have learned: it seems like the options in the bootloader are for restoring just the kernel, in case a kernel update breaks something. snapshots (timeshift is the program/gui that seems to come included with at least mint and ubuntu) save backups of all your system files, so you can roll back if some other update messes something up, or if you personally break something while messing around with your configuration.

thanks, i think this is the intended way of dealing with rollback. i did end up using btrfs assistant to use snapper to take snapshots. probably overkill but honestly most of my fiddling is just to see what i learn doing it, because i’m really not very knowledgeable about linux. i’m hoping if i fiddle with things enough i’ll get some background knowledge which will eventually turn into a more intuitive understanding lol

I had no idea slsk had so much stuff on it, thanks for prompting me to check. A lot of the stuff I was looking for is there.

Just make sure to share my library in turn, correct?
