This seems really klunky to me, and also forces platform dependence, and is fundamentally tied to how posix does things.... Maybe it's not possible, but I suggest that we could pre-define the locations that might be needed: executables (bin) system_executables (sbin) user_executables (./bin) documentation (doc) system_data_files (share ?) user_data_files (./share ) app_configuration (/etc/appname) user_app_configuration (./.app_name : ./Library ) .... This could end up being a pretty big list, but I think it could be finite. Then at install-time, the installer maps these to the appropriate place on the system. It's a little different application, but wxWidgets does this pretty successfully with wxStandardPaths. -Chris > I'm not sure what other subdirectories would be appropriate for > Windows or Mac OS X, although I expect being able to install into > Program Files and Application Data would be interesting for Windows > apps, and into an application folder for Mac OS X. > > It's really the potential for FHS support that drives my interest in > the idea, but if we're going to do something like this at all, it > shouldn't be POSIX specific. > > Cheers, > Nick. > > -- > Nick Coghlan | ncogh...@gmail.com | Brisbane, Australia > _______________________________________________ > Distutils-SIG maillist - Distutils-SIG@python.org > https://mail.python.org/mailman/listinfo/distutils-sig > -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception chris.bar...@noaa.gov
