livecd-rootfs 2.577 source package in Ubuntu

Changelog

livecd-rootfs (2.577) disco; urgency=medium

  [ Tobias Koch ]
  * Detect which core snaps are required and install them on-the-fly.
  * If image has core18 snaps only, automatically preseed snapd.

  [ Michael Hudson-Doyle ]
  * Slim down ubuntu-cpc:minimized builds:
    - Do not include any snaps in ubuntu-cpc:minimized builds (erroring if any
      snap other than lxd is seeded).
    - Install the lxd-installer package instead, which installs the lxd snap
      when invoked.
    - Install lxd snap in unminimize.

  [ Balint Reczey ]
  * Pass --sort=name to tar to make tarballs more reproducible and
    rsync-friendly

  [ Steve Langasek ]
  * Adjust sed command for clarity.
