Bug description:
  If the username is longer than 32 characters the installation will
  fail with:

  Adding user `eca40a93-4fbd-47d5-b084-8945a5499788' ...
  Adding new group `eca40a93-4fbd-47d5-b084-8945a5499788' (1003) ...
  groupadd: 'eca40a93-4fbd-47d5-b084-8945a5499788' is not a valid group name
  adduser: `/usr/sbin/groupadd -g 1003 eca40a93-4fbd-47d5-b084-8945a5499788' returned error code 3. Exiting.

  Ubiquity should limit the username length to 32 character to avoid
  this failure.
