Isn't that a flat out violation of POSIX 8.3 Other Environment Variables?
HOME
The system shall initialize this variable at the time of login to
be a pathname of the user's home directory. See <pwd.h>.
To claim it's not, you have to claim these programs aren't logged in,
in which case where did they get any privileges from?
