Services - check ChkConfig and systemd UnitFiles

This combiner provides information about whether a given service is enabled, using parsers for chkconfig (for RHEL 5 and 6) and systemd list-unit-files (for RHEL 7 and above).

Examples

>>> svcs = shared[Services]
>>> svcs.is_on('atd') # Can be 'atd' or 'atd.service'.
True
>>> svcs.is_on('systemd-journald.service')
True
>>> 'atd' in svcs
True
>>> svcs.service_line('atd')
'atd.service                                 enabled'
>>> 'disabled_service' in svcs
False
>>> 'nonexistent_service' in svcs
False
