Dynamically altering drive mappings at runtime

[Mike Hearn]

.... and on a slightly related note, I am wondering how hard it would be
to allow wine to alter drive mappings at runtime. The reason I ask is
that it'd be nice for the "add drive" dialog in winecfg to use the shell
directory chooser that shows all directories on the system rather than
forcing the user to type in a path manually, which is error prone.

To do that, of course we need a few things:

* the ability to map / if it's not already mapped (or maybe we should
just force / to always be mapped to drive Z in the wine code)
* the ability to switch off drive letters showing through in the
directory chooser dialog, so it's less confusing to see this magic
letter appear.

Thoughts on how hard this is?
thanks -mike

I belive Eric has already proposed being able to dynamically 'mount' parts
of the Unix file system into the Wine file system as part of his file
function rewrite. Eric: how are you progressing on this?

This will probably start another flame war, but I am in favour of the
default Z mapping. However, we could always map Z whenever we need it (e.g.
loading the debugger) with a slight extension of the SetVolumeMountPoint
Win32 API.

I believe there is a registry setting for this under Windows that tells
Shell32 views to not display certain drives. I can't remember where this
setting is though...

slowly, but surely. I do have a running version of the infra, without 
all the required best & whistles yet. Anyway, I'm not 100% sure that 
current drive configuration layout will stay as it is... so, it may not 
be urgent to implement this (we anyway need something in place until all 
the file I/O rewrite has been done)
A+
