Fedora Workstation has been really good in my experience. The available software is shockingly up to date and I haven’t run into much breakage of any kind in the year or so I’ve been using it across 2 systems (despite my best efforts every few months when the urge to tinker hits me). I do occasionally run into issues caused by the default SELinux policies, but they’re not especially difficult to work around if you’re comfortable using the terminal.

I do share your sentiment about the AUR - I definitely miss it at times. That said, Flatpaks and the fact that pre-built RPMs are so commonplace have both softened the blow a lot.

“systemd bad”

I’m not familiar with the specific install/upgrade process on Gentoo so maybe I’m missing something, but what’s wrong with forcing new installations to use time64 and then forcing existing installs to do some kind of offline migration from a live disk a decade or so down the line? I feel like it’s probably somewhat uncommon for an installation of any distro to be used continuously for that amount of time (at least in a desktop context), and if anyone could be expected to be able to handle a manual intervention like this, it’s long-time Gentoo users.

The bonus of this would be that it wouldn’t be necessary to introduce a new lib* folder - the entire system either uses time64 or it doesn’t. Maybe this still wouldn’t be possible though depending on how source packages are distributed; like I said I dont really know Gentoo.

Doesn’t trixie still support like a dozen arches? I think one of the more recent deprecations was MIPS BE which is functionally obsolete in 2024, at least insofar as practically no one is using it to run a modern distribution.
