This sounds like a problem. I'm not sure we can safely assume that non-committers will be using devel/subversion-freebsd. I've long wondered if there were some way to generically checksum every one of these files at install time (Maybe adding a final "#md5:XXXXXXXX" line? Does every file in /etc/ support "#" as a comment start?) Then these checksums could be used to definitively determine: * Files that had local edits (checksum mismatch) * Old files that were different from the system being installed all without relying on VCS IDs or other conventions. In particular, it would be really nice to be able to say "just update everything that doesn't have local edits and let me manually review the rest." Tim
