So I've had enough from partitioning my HDD between Linux and Windows, and I want to go full Linux, my laptop is low end and I tend to keep some development services alive when I work on stuff (like MariaDB's) so I decided to split my HDD into three partitions, a distro (Arch) for my dev stuff, a distro (Pop OS) for gaming, and a huge shared home partition, what are the disadvantages of using a shared home (yes with a shared profile, I still want to access my Steam library from Arch if I want that)
Another thing that concerns me is GRUB, usually when I'm dualbooting with Windows, the Linux distro takes care of the grub stuff, should only a single distro take care of GRUB? or I need to install "the grub package" on both? Do both distros need separate boot partitions? Or a single one for a single distro (like a main distro) will suffice?
Another off topic question, my HDD is partitioned to oblivion, can I safely delete ALL partitions? Including the EFI one? I'm not on a MacBook, a typical 2014 Toshiba that's my laptop
Well, a disavantage I can think of is that if your apps are in different versions, it may be messy. Also, if you share a DE between both environments, it also may become messy
Why don't you try using only one system and see what happens?
Only one system taking care of grub, pls. Grub is already a pain, don't make it even more painful. If you're going to config grub, let PopOS handles it. Only install it after Arch and everything should be fine
If it does not recognize Arch, you may wanna enable os-prober at grub conf, but that's it
If you're ok with losing all the data, it's okay to wipe out everything and let the distro install itself alone
