[Bug 1803162] [NEW] non-dpkg information and broken format in manifest

[Scott Moser]

Public bug reported:

Ubuntu images have been accompanied by a 'manifest' file since at least 10.04.
This manifest file was a list of the dpkg installed packages and their versions.
The format was as output by dpkg-query --show.
That format was
  package-name<tab>version

The offending change was added at
https://bazaar.launchpad.net/~ubuntu-core-dev/livecd-rootfs/trunk/revision/1706

The disco images now contain non-dpkg information in them.
There are a few problems with this:
 a.) the format is now changed.  Some lines will now have 3 fields rather than 2.
 b.) content is not strictly a list of dpkg information.

I understand the desire to have pre-seeded snap information in this file
but believe that the correct way to add representation of that information
is with new files rather extending in non-backwards compatible ways an
existing file.
