This seems reasonable, but will it work properly on non-official CDs - or are
you only proposing this option for official CDs? ie on non-official Cds some
packages are (potentially) replaced by local ones with different MD5sums. I
don't think there is a pre-prepared md5sum.gz file to fish these out of (but
Icould be wrong - I'm thoroughly out of date on how things have chaned in
this area (scanpackages etal) between potato and woody.
