dnf-system-upgrade: s/touch/fixfiles/ to relabel SELinux
This is a personal preference, but the `fixfiles` command is a
convenient binary in Fedora that ships with SELinux to handle relabels.
It does the same thing, but note the use of the `-B` flag.
From the man pages:
> -B:
> If specified with onboot, this fixfiles will record the current date
> in the /.autorelabel file, so that it can be used later to speed up
> labeling. If used with restore, the restore will only affect files
> that were modified today.
I thought I would share this improvement upstream since I use this page
often, but I prefer this way of running more lean SELinux checks.
