Um, ahh, no.  gunzip -c file.gz | bzip2 > file.bz2 can buy up to 25%
more compression (I have seen it, on PPM files---GIF or PNG is rather
more efficient though for that purpose).  But that's probably not
enough, and bzipping an already gzipped file rarely buys as much as 5%
(which is pretty spectacular in itself, though).

Unfortunately, AFAIK bzip2 does not come in RPM format yet.  So you'll 
have to get it yourself.  Sources for a stable version can be found at 
any sunsite mirror.

you can also make a multivolume tar file (tar --create --file=/dev/fd0
package.rpm, you may need a flag to tell tar it's multi-volume, but I
think tar figures this out for you).  This has the advantage that tar
does the accounting, not you.
