Description of problem:
Appeared on upgrade from F27 to F28. This laptop does not have Thunderbolt (it's about a decade too old for that).
SELinux is preventing (boltd) from 'create' accesses on the directory boltd.

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

If you believe that (boltd) should be allowed create access on the boltd directory 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:
# ausearch -c '(boltd)' --raw | audit2allow -M my-boltd
# semodule -X 300 -i my-boltd.pp
