Just a heads-up for the newer Fedora Atomic users out there, and a focus on this part for the longer-term users:
This only impacts new installations and not updated systems thus systems installed from artifacts before those releases are not impacted (Fedora 38 or earlier).
Isn’t selinux enabled by default? Hence, most won’t be affected.
I’m not sure you’re right, I can’t find information regarding whether users are confined by default on Fedora (Red Hat docs seem to indicate the users are unconfined by default).
Edit: They are not, see https://docs.fedoraproject.org/en-US/quick-docs/selinux-getting-started/#_selinux_examples, specifically:
ls -Z in any user home will show they are unconfined_u (so will id -Z).
