agreed, the plain text db is the right way to do it.
OTOH, it would be nice if dpkg did what apt does and uses a binary db
"cache" to speed up operations...updating both binary and text versions
as changes are made.
the text version would be considered authoritative (or "source code")
and the binary db would be the faster, "compiled" version. if the binary
version ever got corrupted for any reason, it could be regenerated
quickly from the text version.
dpkg would also need to detect whether the text version was newer than
the binary version and, if so, automatically rebuild the binary.
nice idea, perhaps...but i don't know how practical it is or whether the
time needed to maintain the binary db would more than offset the time
