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="!virtual/cron virtual/mta >=sys-process/cronbase-0.2.1-r3" PROVIDE="virtual/cron" # docrondir [ dir ] [ perms ] # # Creates crontab directory # # Both arguments are optional.
