I've had to run postfix set-permissions on my box to resolve a few ownership issues. On this platform (Debian Lenny) a few things aren't what set-permissions expects to find-- largely man pages that aren't compressed, slightly different pathing, map files that aren't necessarily installed, etc.
What I haven't noticed is a way to get set-permissions to note the error (stdout or stderr would be fine) but continue on past failure to address the rest of its checklist. Having to manually unzip large numbers of man pages just to get permissions set on stuff that's more important is frustrating. Would implementing something like this be difficult? I'm prepared to hack on it a bit myself if needed. -- Corey / KB1JWQ
