Fwd: NSUserName() returns wrong user and..

[Richard Frith-Macdonald]

Any thoughts on this?

Does anyone object to changing NSUserName() to return the name
associated with geteuid() rather than the LOGNAME environment
variable?

Should the name be (as currently) cached, or should the function
check the effective user id every time it is called?

At present there is an extra function GSSetUserName() which can
be used to manually set the username and reset the user defaults
system ... but if NSUserName() rechecked geteuid() every time it
was called, it could reset the user defaults system itsself.
