You've got more problems that just PA then. For example, some Firefox addons won't be compatible between the different versions, some binaries that you have in your home directory (or a subdirectory thereof) are going to need be built on RHEL4 and have the corresponding compat- stuff installed (even if it's available). The list of cross-release compatibilities is endless -- I know because I get bitten by it regularly -- and I don't think that the PA database format even comes close to being tricky. jch
