Using these # functions also ensures that permissions are *always* reset, # preventing the accidental installation of files with wrong perms. # # NOTE on defaults: the default settings in the below functions were # chosen based on the most common setting among cron ebuilds. # # Please assign any bugs regarding this eclass to cron-bugs@gentoo.org. inherit eutils flag-o-matic EXPORT_FUNCTIONS pkg_postinst SLOT="0" DEPEND=">=sys-apps/sed-4.0.5" RDEPEND=">=sys-process/cronbase-0.3.2" for pn in vixie-cron bcron cronie dcron fcron; do [[ ${pn} == "${PN}" ]] || RDEPEND="${RDEPEND} !sys-process/${pn}" done # @FUNCTION: docrondir # @USAGE: [ dir ] [ perms ] # @DESCRIPTION: # Creates crontab directory # # Both arguments are optional.
