Description Eric Blake 2011-06-28 21:20:42 UTC
SELinux is preventing /usr/sbin/prelink from 'read' accesses on the file /lib/systemd/system/fedora-autorelabel-mark.service.

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

If you believe that prelink should be allowed read access on the fedora-autorelabel-mark.service 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 prelink /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Looks like a leak.

What does

# stat /lib/systemd/system/fedora-autorelabel-mark.service

The AVC happened while I was doing a 'yum upgrade' on rawhide, so I'm not sure if it was a one-time event.

Ok, please reopen if this happens again.
