Yes, recent  (like last 6 months or so) rpm has dropped converting
file lists from what was used by rpm-3.0.x. Sun has had like 6 years
to convert, enuf already.

I'll attach a rpm2cpio.sh that is even more portable than rpm2cpio.

The Solaris port of rpm-4.4.8 is proceeding swimmingly, thanks to Tim  
Moony and Frank Cusack.

Details are at https://lists.dulug.duke.edu/pipermail/rpm-devel.

Meanwhile, if all you need is signature verification of a package,  
then use
the attached script which extracts the plaintext from a *.rpm and  
uses gpg to verify.

The script is very similar to rpm2cpio.sh.

.(Caveat Emptor: script might need adjustments, dunno if ever used on  
solaris)
