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.
