Could you please explain the thought process that led you to settle on Fedora? Thanks!
No other distro has the same level of immutable tooling or support for immutable variants at this time. Also, Fedora has selinux tooling and enforcing mode out of the box and they're working on further selinux improvements upstream, so we'll get that for free.
And it's also mainly geared towards server use cases, whereas this project is mainly focused on desktop users.
