If I’m trying to look up how to do terminal stuff to install something not on flatpak, 99% of the time the instructions are for regular Fedora, not Silverblue.
This is solved by the various ublue images and distrobox generally. Distrobox basically lets you run those install instructions as natively as possible. Its a bit like WINE but for all linux distros. For example, I can install a .deb file to my system with distrobox, or I could pull from Arch’s AUR. Distrobox lets you be pretty lazy, it works most of the time, though some applications don’t seem to like it. And by the way, you can download a .rpm file and layer it using rpm-ostree install [.rpm filelocation] if all else fails.
Generally, I feel like Fedora Atomic is the best middleground for linux these days. It really incentivizes the users to use containers, which are far more secure than the permissions anarchy of normal linux. Its easy enough to daily drive too.
What feature does ShareX provide that Spectacle doesnt? You can share to imgur, telegram, etc with it.
Bazzite has a different kernel thats tweaked for performance, thats probably what it is
