I’m on Linux for a couple of years and I love it. Distrohoping never interested me though, I’m content with my flavour. But I need to reinstall my OS soon and it gives me headaches. So many settings I changed, applications I installed, configured and forgot about.
Now I read about all you guys constantly distrohopping for fun, how do you even do this? Do you start from scratch, explore everything and leave after months of putting in all the work of making an OS your own!? Or do you just casually check it out a couple of days? What do you do with all your music, pictures, addons, portable software?
You don’t actually require a separate partition - you just need to not reformat the current one when reinstalling. Most distros I have seen will delete system folders if you don’t format but will always leave the home folder intact. Manually deleting the system folders is also an option if the installer does not.
TBH I am not sure a separate partition actually buys you anything but false confidence (which we do sometimes need ;) ). During the partitioning phase you can easily delete or format the wrong one (hell, if you only have one then it is less error prone to skip it all together). And after that step the drives are mounted and there is nothing protecting your files from the installer deleting them. It is just installers don’t touch the home folder or anything other then the system ones if it is on one partition or 50 different ones - it just sees the files in the directory it wants to install to. The only way a separate partition would add protection is if it were mounted after the install - which I do not know of any installer that actually does that.
As with anything. ALWAYS backup the data you care about before installing a new OS. The separate partition does NOT protect your data from deletion in any way. Leaving your home folder is simply a convenience option so you don’t need to restore all your files after the installation - not a replacement for a backup.
