Ehm.. I think this is what he meant, right?

.. unless he can get the mount points to work relative to a root mount. 
His fstabs idea might work here: you mount a single root (under which you 
*must* have an etc directory with at least an fstabs file), read the 
fstabs file and mount the rest, using only POSIX paths as reference. 
That's why I told him to "write and contribute". I think the idea might be 
a good one - especially if he develops it and tests it on his Cygwin fork.

Well.. it might be possible to introduce a configuration option at compile
time, setting the defines as Igor suggested yesterday. If he could write a
patch and get it accepted he would no longer need a fork.

As Cliff Hones suggested (also yesterday), it may well be a good idea to 
start supporting this kind of thing. If Ben wants to put some time and 
effort into it, forking off a Cygwin, developing the capability to have 
two run at the same time, that could lead to a merge with the current 
Cygwin to let Cygwin have that capability (and if he can get the mount 
points out of the registry, I think Chris and Corinna may be interested in 
that as well).

Anything in that direction would have to start off with a fork, though..
