# TuneD rules for recommend_profile.
#
# Syntax:
# [PROFILE1]
# KEYWORD11=RE11
# KEYWORD21=RE12
#
# [PROFILE2]
# KEYWORD21=RE21
# KEYWORD22=RE22
# 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.
