>Organization:
The NetBSU Login
>Environment:
>Description:
The su(1) command has no way to do setlogin(), so getlogin() always returns the original caller's login name.
>How-To-Repeat:
try to run automatic tests involving cvs (which uses getlogin() if getuid() == 0) in a chroot with su
>Fix:
Yes, please!
