lvm2/conf/metadata_profile_template.profile.in

# This is a metadata profile template for the LVM2 system.
#
# It contains all configuration settings that are customizable by metadata
# profiles. To create a new metadata profile, select the settings you want
# to customize and add them in a new file named <profile_name>.profile.
# Then install the new profile in a directory as defined by config/profile_dir
# setting found in @DEFAULT_SYS_DIR@/lvm.conf file.
#
# Metadata profiles can be referenced by using the --metadataprofile LVM2
# command line option.
#
# Refer to 'man lvm.conf' for further information about profiles and
# general configuration file layout.
