Description Moritz Baumann 2013-06-05 18:50:15 UTC
Description of problem:
1) timedatectl set-local-rtc 1
2) AVC alert showed up
SELinux is preventing /usr/lib/systemd/systemd-timedated from 'create' accesses on the file .adjtimeXXdfqS.

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

If you believe that systemd-timedated should be allowed create access on the .adjtimeXXdfqS file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# grep systemd-timedat /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Miroslav Grepl 2013-06-06 06:48:24 UTC
Back ported from F19.

    Allow systemd_timedate_t to manage /etc/adjtime.
    Add transition rules to unconfined domains and to sysadm_t to create /etc/adjtime
    with the proper label.
