Sorry, I was not replying to you (not an insult). I assume you are interacting from Mastodon from the format of the comment, and getting pinged on replies to other comments (?). I mean, you do you, absolutely not going to diss people who want absolute control over their system. But immutable distros are fundamentally an entirely philosophically different approach from how traditional Linux distros have been packaged and managed in the past. That said, I didn’t make the installers, I’m just reporting what has been my recent experience toying with immutable distros. The whole point is to automate as much as possible of the deployment and management of an OS, and do the least amount of tedious manual troubleshooting. If you don’t like that, all the other distros are still there, they haven’t gone anywhere. The current recommendation for Fedora Atomic based distros is to use specialized tools like Universal Blue that allows the user absolute freedom to deterministically configure a Fedora install that results in an immutable OS. And the installer is actually pretty flexible to let you choose how you want the disks laid out. But, the idea is that you should let the installer do its job, that’s for what it was made. If you want to do everything by hand just use Arch, that’s what Arch is for.
Maybe they’ll fix the sddm custom theming? It’s currently broken on all immutables and doesn’t allow custom themes.
