No longer able to install debs in early command

Binary package hint: casper

Version: 1.217

Within the last few iterations of casper there has been some speed improvements. One of the particular improvements is to have a persistent debconf-communicate process running. This causes a conflict with being able to install debs via either an early command or drivers update media.

Colin recommended this patch:

Unfortunately that doesn't seem to do the trick.
