A question for the group: Where should cabal-install's various files go?

Here's my Windows-user-opinions. I am not sure they follow any real guidelines, if there are such for packaging systems in Windows.

...

...

Files: server.list - one line config file with the Hackage server location, basically never modified; package.list - the listing of packages available on the Hackage server; packages/ - the directory in which all of the downloaded packages are stored.

Options: 1) Proper: /etc/server.list,

Definitely!

On Windows, registry or file next to executable. Registry path HKCU\Software\Cabal\Cabal-install\ od HKLM\Software\Cabal\Cabal-install\ depending mode: user-only vs Administrator (or however rights go).

...

...

/var/local/lib/cabal-install/package.list, /var/local/lib/cabal-install/packages/. A bit dogmatic and I'm not sure how it maps onto non-*nix systems, but it's the Right Thing to do on *nix.

I don't know about /var/local. There's nothing in that directory on my Debian system. /var/lib maybe, or /var/cache.

In Windows, this would is a question user answer when during install. Path should be stored in registry or file next to executable.

2) Easy: everything goes in $lib-prefix/cabal-install. Isn't the prettiest solution, but it's functional. Maps onto Windows well. Users will never directly see or use these files, so $lib-prefix/cabal-install. (GHC does this with its package.conf.)

I think that'll be broken for Debian which doesn't want random files in /usr/lib changing that much.

I'd think this would be ok for most Windows users, but it's sort of unorganised. HTH, --Esa
