Busybox has a really really minimal core re-implementation of rpm/cpio.
~ It's too minimal for real use, in fact, but it does work.  A few months
ago I did some work on it adding a "database" maintained in /var/lib/rpm
consisting of just the header part of all installed packages.  It has a
trawl through them to determine package requires and suchlike on -i -u
or -e.  The benefit is mainly thanks to the original implementation I
added to, the thing is incredibly lean in terms of memory use and
footprint, although since it was designed for an embedded RPM-based
distro scalability is a bit poor since there is no database but a bunch
of files to wander through and 'bunch' could be expected to be less than
20 for the use it was written for.

It's a http://warmcat.com/rpm.c if anyone is interested; needs to go in
./archival in the Busybox tree replacing the one that's there.
