Description Mads Kiilerich 2011-09-12 08:53:32 UTC
SELinux is preventing /bin/systemd-tmpfiles from 'read' accesses on the directory isolinux.

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

If you believe that systemd-tmpfiles should be allowed read access on the isolinux 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:
# grep systemd-tmpfile /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Mads Kiilerich 2011-09-12 08:55:45 UTC
I happened to have
drwxrwxr-x. mk mk system_u:object_r:iso9660_t:s0   /tmp/isolinux/

I would expect that either
* systemd had permissions to remove _everything_ in /tmp, or
* systemd didn't try to remove anything it didn't have permissions to - and log it "properly", or
* such denials were silent

Comment 3 Daniel Walsh 2011-09-12 19:08:50 UTC
Well I guess in this case we can dontaudit it.

But lets add

fs_list_all(systemd_tmpfiles_t)
