A very dumb question probably, but I'm new to using Linux so I lack a lot of understanding: I'm on Bazzite atm. Would there be a simple way to switch to blend OS without wiping everything? Like a rebase? Probably not but I figured it's worth a shot to ask xD

No such thing, we all start somewhere! :)

Anyway, you could in fact do that if you were thinking of trying out other Fedora Atomic images such as Silverblue and whatnot (see also the ublue page listing tons of others, including your bazzite!). This uses different tooling, so unfortunately not in this case.

Ooh, not just yet (in essence, it’d be hard to migrate over from the system used in Fedora Atomic to that used by blendOS) :( We’re working on a migration script for users from regular ole’ Arch Linux, though.

(disclaimer: blendOS dev here)

bazzite is fedora based? If so, your filesystem is btrfs and your /home is a subvolume, same as your / (root). you can install a new operating system in a btrfs subvolume (e.g. /blendosroot), then have systemd-boot or grub mount it as root and mount your existing home from it.

sadly, there's no noob-friendly way to achieve this, but if you're adventurous, you have enough search terms to make it happen.

I'm new too but I separated by root and home partitions this last install to try and allow that.

This use case would be covered by bootc, but BlendOS doesn’t have support by the looks of it atm

Yes, but only if you have separate partitions for root, home, boot and swap. Otherwise, it is going to be painful.

Is there a guide or any educational material on this? I'm about to swap to Linux (some fedora distro focused on gaming) and I'm interested in potentially one day swapping to arch after I've gotten my toes wet. Doing a bit of extra work and planning ahead to make that easier sounds nice.

There's probably some generic tutorial out there, but since I've started to separate partitions after moving to NixOS and Guix, and self-learnt this, I'm not sure what would be a better resource for you.

Yeah I don't as in the bazzite installer it's a real pain to set it up manually (also not allowing you to spread the partitions over multiple drives during the initial setup)

Isn't that kind of the point of keeping / and /home on separate partitions or subvolumes/pools?
