Ubuntu upstart migration completed.

WARNING:

   This is a "lazy" migration: Ubuntu init scripts are migrated
   similar, but not identical. Some services have been skipped, because
   they are not necessary with cinit or in general.

   Check /etc/cinit before rebooting with cinit!

KNOWN BUGS:

   S20checkroot.sh: Only / is being fscked, other partitions are ignored.

HINT:

   Make sure init=/sbin/cinit is set in your bootloader.
