I have tried it on several distros before and it always causes problems because you get a million more packages intermingled with your already installed packages and sometimes you get conflicts or whatever. But it usually messes up my system. is there a safe way to have several desktops installed? or do you pretty much install a new one then remove the old one? thanks
Any package manager with pre install hooks should work. I know someone has written the necessary hooks for pacman, if Timeshift is in your distro’s package standard package manager I bet there’s a hook pre-written for you as well.
If there isn’t, Timeshift can also take daily/weekly/monthly/per-boot snapshots (with an optional limit for each separate type to keep). Because snapshots only track the differences, and /home is excluded by default, snapshots are generally smaller than a gigabyte or so because they only track OS updates and such. Older snapshots will grow in size as the difference between them and the current system state grows, but 9 months and an upgrade from Ubuntu 20.04 to 22.04 to 22.10 only took up 54GB on a 1TB disk.
I like the “take a snapshot each boot” option because you can revert every boot rather than specific actions, especially when your package manager lacks the necessary hooks.
Thats really good to know. Thanks for taking the time to explain that.
