Mighty Haskellers, I'm afraid we've never had a very good story about how to run "register" and "unregister" on a target machine which is different from the machine that a cabal package was built on. This comes up when building Debian or RPM packages which get copied into a temporary location, packaged up, and shipped off to an end user's machine. The closest I've come is to say that after installing into a temporary directory, you should bring the Setup script (and the .cabal file, and the .installed-pkg-info file) along and rerun it on the target machine, which probably has cabal anyway. This should work fine, but it's a little heavy handed for a one-line call to ghc-pkg. Yesterday someone suggested that instead of doing this, we could emit a little shell script / batch file (which might even contain the .installed-pkg-info file) and just run that on the target machine. So I'm thinking of adding a flag to register and unregister, maybe --dry-run or something which does _not_ register right away, but rather emits such a script. This is actually a pretty small change, but I wanted to check with you folks before adding it, since we're so close to a release. Does anyone see any problems with this? peace, isaac
