[gentoo-user] Sharing of wine drives between different users of same machine

[Mark David Dumlao]

After an (in?)convenient crash of a particular operating system which I have
dual-booted with Gentoo for a while; I am going to reinstall it. My main
issue though, for that particular operating system is that the shared
c_drive of different wine users was shared there, and it annoys me that
certain games now need some reinstalling (fortunately, the save files are in
a safe place).

Well since I'm going to go and do something a bit tedious anyway, I might as
well do it right.

I was wondering what strategies you guys use for sharing wine drives between
different users. I have 3 kids using the same box for games; wine was one of
the main features of using that box. I have previously done some of the
following:
(1) Everyone's .wine -> c:\wine (ntfs drive)
which makes some sense, but the bad thing is that usernames are preserved
across users.
(2) Everyone's c_drive -> c:\wine (ntfs drive)
Which also makes some sense, but I wonder if registry issues that are user
specific point to the wrong places.
(3) Everyone's program files -> c:\wine (ntfs drive)
Which does solve the issue of saving space; but the problem is that registry
entries from installing programs don't get shared.

What's the proper way to multi-seat wine to make it behave like a multi-user
Windows environment?
