The right thing to do is to change the base-files package to utilize
/proc/cygdrive.  It's a vrtual symlink pointing to the actual cygdrive
prefix currently in use.  If these symlinks under /etc used the
/proc/cygdrive symlink, they would work all the time, independenly of
the actual cygdrive prefix.

Achim, any chance to tweak base-file accordingly?
