Description of problem:
This popped up during system update.
SELinux is preventing systemd-gpt-aut from 'ioctl' accesses on the blk_file /dev/sda.

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

If you believe that systemd-gpt-aut should be allowed ioctl access on the sda blk_file 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-gpt-aut /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
