Fedora 42 as dom0 in Qubes 4.3

[alimirjamali]

I have been using (testing) Fedora 42 as my default Templates for over a week (including minimal Fedora 42 templates for ServiceVMs). Details here:

Fedora 42 repositories are being tested by testing team

Update: Fedora 42 is good. It is hard to explain. But I mean noticeably good. Maybe it is the underlying GCC 15, LLVM 19 and Golang 1.24 compilers optimizations which made everything noticeably faster. Or maybe I am deluded. Fedora 42 official release date is 2025-04-22 and Fedora 40 EOL date 2025-05-28 For those who are still on Fedora 40 and have not upgraded to Fedora 41, Maybe if Qubes OS project manages to release stable Fedora 42 templates before 40 EOL, it would be justifiable to skip …

In addition to the explanation in the above post, Fedora 42 has some other cool features. Bees is packaged for it (For BTRFS de-duplication if you need it). Xfce 4.20 has experimental Wayland support features. A pretty new Anaconda installer (which itself is wayland based), DNF/RPM CoW, etc.

Having said that, we do not have enough time. It is more feasible to backport highly essential packages to Fedora 41 for dom0 rather than supporting all of the above for Qubes OS 4.3 (as there are a tone of them). And Fedora 42 templates could be individually provided. I believe we will have to wait for Qubes OS 4.4 (or maybe 4.3.1) for Fedora 42 support.
