This is very strange, I have no idea why SELinux update would do this,
and suspect that something else might have gone wrong.  Were there other
packages in the update?

I will update my F10 and see what is going on.

Could be someone is doing a chcon -t usr_t in a post install script?

selinux-policy should only be doing the equivalent of a restorecon -vR
in its post install.  Actually executes fixfiles
"fixfiles -C ${FILE_CONTEXT}.pre restore"

Which figures out what was different between the old file context and
the new and runs restorecon on them.
