# This class creates the initial aide database durning
# the build cycle allowing for that set being skipped during boot
# It has an additional benefit of having not being tamper with
# after build.
#
# To have the aide db created during build
# 1. Extend local.conf:
# INHERIT += "adie-init-db"
#
# These are the defaults as defined in aide-base.bbclass
# They can be overriden in your local.conf or other distro include
#
# To define where the share directory should be.
# STAGING_AIDE_DIR = "${TMPDIR}/work-shared/${MACHINE}/aida"
#
# To define which directories should be inclued in a scan
# AIDE_INCLUDE_DIRS ?= "/lib"
#
# To exclude directories and files from being scanned
# AIDE_SKIP_DIRS ?= "/lib/modules/.\*"

# To controll if a db init should happen at postint

# To cotroll if a db recan should be run at postinit
