When you speak of this in terms of processes, I think you mean that the Cygwin DLL would need to filter the environment, which sounds heavy-handed.

If you mean that /etc/profile and such will do the filtering, that could work.

This isn’t a second option, it’s an implementation design for option 1.

Here’s an interesting experiment to try on your non-Cygwin POSIX boxes:

    $ HOME=/dfjkshkds bash -l
    $ echo $HOME

Guess what it prints.

Hint: It isn’t the second-to-last field in /etc/passwd. :)




Spoiler: Apparently Cygwin is already doing the standard thing.
