From b83f8fcaffa542498c5698a3a161b9967ac1d3d6 Mon Sep 17 00:00:00 2001 From: Dimitri John Ledkov Date: Sat, 2 Jul 2016 19:16:01 +0100 Subject: mdadm (3.4-2) unstable; urgency=low * Reneable incremental assembly * Rely on udev to assemble incremental arrays * In environments with systemd rely on mdadm-last-resort@.timer|.service units to activate degrated raids * In environments initramfs-tools initrd (no systemd) add local-block script to do the same after 2/3rds of root delay iteration * Drop local-top initramfs script * Drop dependency on initscripts package * Drop INITRDSTART support * Drop mdadm-raid init script * Drop ancient preinst * In mdadm.init remove dependency on mdadm-raid * In mdadm.init check, and bail out running in a container * In mdadm.config drop mdadm/autostart logic * Drop CREATE stanzas from mkconf and don't include them in the initramfs. The generated defaults, are the compiled-in defaults. And the current one generates warnings when running mdadm in the initramfs, as there is no passwd|group files to resolve root/disk uid/gid. Closes: 717609 * Adapt changes and formatting of initramfs hook from Ubuntu * Bump standards version to 3.9.7, no changes required * Fix copyright-refers-to-symlink-license * Closes: #781172, #796624, #769201, #813335, #632401, #804973, #714155, #770002, #737132, #675452, #726390, #813637, #814036. # imported from the archive --- debian/initramfs/hook | 110 +++++++++++++++++++++++++++++++++++ debian/initramfs/script.local-block | 44 ++++++++++++++ debian/initramfs/script.local-bottom | 3 + 3 files changed, 157 insertions(+) create mode 100644 debian/initramfs/hook create mode 100644 debian/initramfs/script.local-block create mode 100644 debian/initramfs/script.local-bottom (limited to 'debian/initramfs') diff --git a/debian/initramfs/hook b/debian/initramfs/hook new file mode 100644 index 00000000..ae7d4d18 --- /dev/null +++ b/debian/initramfs/hook @@ -0,0 +1,110 @@ +#!/bin/sh +# +# Copyright © 2006-2008 Martin F.
