Changelog parent: d43f1aeb9c

New changelog entries:
  [ Michael Vogt ]
  * do not leave some packages in ^rc state on snappy/ubuntu-core
    (LP: #1428115). Thanks to Daniel Holbach
  [ Oliver Grawert ]
  * put FLASH_KERNEL_SKIP=true into /etc/environment on phones, this will
    prevent the systems from trying to flash an updated initrd automatically
    in case you call update-initramfs or install your own kernel package on a
    nexus device where this is supported, please call flash-kernel manually
    after unsetting the variable in your work environment.
