Description Horst H. von Brand 2011-01-17 12:31:05 UTC
SELinux is preventing /lib/systemd/systemd-tmpfiles from 'write' accesses on the sock_file socket.

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

If you believe that systemd-tmpfiles should be allowed write access on the socket sock_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-tmpfile /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Daniel Walsh 2011-01-17 15:35:21 UTC
systemd_tmpfiles needs auth_use_nsswitch

grep getpw  *tmp*
tmpfiles.c:                else if ((p = getpwnam(user)))
