Description Jóhann B. Guðmundsson 2011-03-31 12:32:26 UTC
SELinux is preventing /bin/systemd-notify from 'write' accesses on the directory readahead.

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

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