Which core packages?

UDD query to get a list of core packages (172 as of 2014-09-19): 

SELECT DISTINCT source
  FROM packages
 WHERE release = 'sid'
   AND section != 'debian-installer'
   AND (   essential = 'yes'
        OR build_essential = 'yes'
        OR priority IN ('required', 'important', 'standard')
       )
 ORDER BY source;

Pass

Not using `dh`

Without dh, it means that dh_fixmtimes is not going to get called, so the timestamps in data.tar will differ.

Using cdbs instead:

Failing

Unbuildable
