is it a good idea to have /home on a separate partition or drive?
@tc001 It can be! If you do, it makes it easier to migrate from distro to distro, or to just nuke yours and reinstall. As long as you don't reformat the /home partition/drive, you can just keep your files, preferences, etc.
You still need to reinstall the software you had, but all the stuff in your home folder stays put.
@tc001 If you're just wanting to move your home folder, you shouldn't need to reinstall anything.
You could copy your home folder to another drive or partition with the `rsync` command. It's not too tricky, but might take a few minutes to plan out before you do it. Then, once it's copied, you can set up the computer to mount that drive/partition as /home (that might take a few reboots and some config file editing, depending on your setup)
You'd only need to reinstall if you reinstall the OS.
