What's the rationale for this?

As written, this is a new security hole.  Any Hurd-specific environment
variables affecting libc behavior have to both use __secure_getenv and
be listed in EXTRA_UNSECURE_ENVVARS.  It doesn't fit any existing use
to have an open-ended space of environment variable names, rather than
just a fixed name, so you'd have to change that too.

But, I don't see any need for this at all.  The Hurdish thing to do is
to run with a crdir that has /servers/socket interposed with whatever
you wanted.  In the Hurd, /servers is no more magical than /etc or any
other file name built into libc and other such places.  The way to
change the file name resolution your processes see is with translators.


Thanks,
