Preinst scripts may expect all Essential:yes packages (and their
dependencies) to be installed and configured on the system.  The
exception is obviously preinst scripts of Essential packages; they may
expect all those packages to be unpacked.

So the proper order of events would be:
- unpack essential packages
- run preinst of essential packages
- run postinst of essential packages
- run preinst of other packages
- unpack other packages
- run postinst of other packages

I'm not surprised if during bootstrap all Priority:standard and higher
packages are treated the same, even if not all of them are Essential.

Thanks,
