# +ROOT_ACTIONS - run actions requiring superuser privileges
#
# Usage: ./+ROOT_ACTIONS ADD|REMOVE [metadatadir]
#
# This script runs certain actions that require superuser privileges.
# If such privileges are not available, then simply output a message
# asking the user to run this script with the appropriate elevated
# privileges.
#
# Lines starting with "# SYMLINK: " are data read by this script that
# name the source paths and corresponding symlink that is managed by
# this script.  If the symlink path is relative, then it is taken to be
# relative to ${PKG_PREFIX}.  The source path is always unchanged.
