>Description:

On a machine where root has a csh style shell (tcsh from pkgsrc in my case),
some atf tests do not work - something strange happens when scripts call
su(1).

First noticed in sparc64 test runs, but I can also reproduce it on amd64; there
may be some interaction with my tcsh startup scripts.

>How-To-Repeat:

As root:
chsh to /usr/pkg/bin/tcsh
cd /usr/tests/fs/tmpfs && atf-run t_create

>Fix:
n/a
