From 2fb5886fd739f47d811ea0d3f595d50250de5646 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Christoph=20M=C3=BCllner?= Date: Mon, 20 Jul 2020 17:20:10 +0200 Subject: [PATCH] package/urandom-scripts: new package MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The init script S20urandom is used to preserve the kernel's RNG seed between reboots. This functionality is not required for the package "initscripts". Further there are use-cases where this script should not be installed at all (e.g. systems that only have read-only partitions), but that's currently not possible as the script is a mandatory part of the package "initscripts". Let's move the script into its own package "urandom-scripts" and select it, if the default skeleton is enabled. This maintains backward-compatibility and allows to deselect it. Signed-off-by: Christoph Müllner [yann.morin.1998@free.fr: - extend help text - default y if initscripts (instead of skeleton default) - allow use with openRC, but not systemd ] Signed-off-by: Yann E.
