Ummm, an intelligent user would still figure this out. It seems that
you are trying to camouflage that cygwin is being used. Security
through obscurity will not stop a user. There is also more that you
need to change then just the dll name. There are the registry keys,
uname output, plus probably a dozen other things that I'm not aware of.
What might be better is to setup the cygwin environment as admin on an
NTFS partition and then make sure the user doesn't have admin
privileges. That way a user wouldn't be able to change the default
configuration. They still might be able to figure out how to recompile
items and make them work and screw up their own environment, but
nothing that an admin couldn't quickly fix.
Enjoy,
Peter
