a simple question: why unpack RPMS? Clearly Linux itself can be run compressed (Live CDs do that now). Given the bottleneck of slow disk and fast CPU it might be faster to load the compressed image, unpack it, and execute it then it would to load it directly. Yet another feature is that RPMS don't have to explode all over the filesystem so upgrading is just a copy operation. Is anyone aware of an effort to make an RPM filesystem? Could such a filesystem run in user space? RPMS might not be the very best format for compressed packages but they could make a convenient starting point. Fedora extras would be so much sweeter if you only needed to mount the DVD containing the RPMS and it all "just worked". Tim Daly axiom@xxxxxxxxxx daly@xxxxxxxx
