Changes in v2:
 - break up the previously single patch into refactoring + fix
 - add a fix for prematurely failing rootfs_do_unounts

Jan Kiszka (3):
  image: Avoid breaking the build when mounts are no longer present on
    umount
  rootfs: Provide rootfs_do_umounts
  initramfs: Add missing umounts after generation

For v2:
Tested-by: Florian Bezdeka <florian.bezdeka@siemens.com>

But:
We're not done yet. There are two more calls to rootfs_do_mounts that
are not yet pared with rootfs_do_unmounts calls. The one in
do_rootfs_postprocess is the problematic one from the other thread on
the ML. (Anton is now in CC as well)

I'm currently testing (on top of v2):
