-    # KEYWORD21=RE21

-
-    # KEYWORD can be:
-    # virt            - for RE to match output of virt-what
-    # system          - for RE to match content of /etc/system-release-cpe
-    # process         - for RE to match running processes. It can have arbitrary
-    #                   suffix, all process* lines have to match for the PROFILE
-    #                   to match (i.e. the AND operator)
-    # /FILE           - for RE to match content of the FILE, e.g.:
-    #                   '/etc/passwd=.+'. If file doesn't exist, its RE will not
-    #                   match.
-    # chassis_type    - for RE to match the chassis type as reported by dmidecode
-    # syspurpose_role - for RE to match the system role as reported by syspurpose
-
-    # All REs for all KEYWORDs have to match for PROFILE to match (i.e. the AND operator).
-    # If 'virt' or 'system' is not specified, it matches for every string.
-    # If 'virt' or 'system' is empty, i.e. 'virt=', it matches only empty string (alias for '^$').
-    # If several profiles matched, the first match is taken.
-    #
-    # Limitation:
-    # Each profile can be specified only once, because there cannot be
-    # multiple sections in the configuration file with the same name
-    # (ConfigParser limitation).
-    # If there is a need to specify the profile multiple times, unique
-    # suffix like ',ANYSTRING' can be used. Everything after the last ','
-    # is stripped by the parser, e.g.:
-    #
-    # [balanced,1]
-    # /FILE1=RE1
-    #
-    # [balanced,2]
-    # /FILE2=RE2
-    #
-    # This will set 'balanced' profile in case there is FILE1 matching RE1 or
-    # FILE2 matching RE2 or both.
