That leaves out drives other than "c:", unlike Eli's version.
Do we always want to discard that possibility?
If the "c:/" isn't there, then at least a "c/" could be, so that
you can still map a "d:" using directories or symlinks on
the host, something like this:

 /sysroot/c/path/to/a
 /sysroot/d/path/to/b

Leaving the ':' in:

 /sysroot/c:/path/to/a
 /sysroot/d:/path/to/b

The former, without ':' allows using the same sysroot
on a Windows host, since I don't think you can create
directories with ':' there.

(
 Wine maps a "sysroot" similarly:

  ls -als .wine/dosdevices/
  c: -> ../harddiskvolume1
  d: -> ../harddiskvolume2
  z: -> /

 Look, a file named 'c:' on a unix box! Okay, this
 case doesn't really count.  :-)
)


Worth considering, IMHO, perhaps as an optional mode,
similar (or exactly like) to Daniel's tri-state
setting suggestion.
