Why boot and swap? Even /root is probably unnecessary.

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.

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)
