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.
