Description Jóhann B. Guðmundsson 2011-03-31 12:51:13 UTC
SELinux is preventing /bin/systemd-tty-ask-password-agent from 'write' accesses on the directory systemd.

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

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