The logname documentation is silent concerning its implementation.
It appears to rely on getlogin(), which is known to have limitations
(or bugs)[*]. Even though such limitations may be documented in the
getlogin documentation, the user isn't necessarily aware that they
affect logname.

and the getlogin(3) man page under GNU/Linux.
