Description of problem:
Triggered after update. Test done on Rawhide using Gnome Boxes 
SELinux is preventing /usr/lib/systemd/systemd-logind from 'unmount' accesses on the filesystem .

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that systemd-logind should be allowed unmount access on the  filesystem by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep systemd-logind /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
