Indeed that would be the "correct" fix.  That's what I said!  ;-)
However we do need an extensible utmp/wtmp file format first.  I can
think of at least a half-dozen ways of doing this off the top of my head
though so until there's a bit more consensus I'm not about to pick one
of them and implement it on my own.

Also, unless you either eliminate the (bogus IMO) setlogin()/getlogin()
system calls, or allow arbitrary length crap to be stored in the kernel,
there's still going to have to be a real hard limit somewhere.  I'd
rather not have arbitrary length per-session or per-process data in my
kernel, even if it can only be put there by root.  In fact I'd rather
the kernel went back to never knowing the user-name at all, ever, Period.

In the mean time I'd REALLY like to see things at least made internally
consistent!  Hell even the documentation isn't consistent with the
current inconsistency!  Add the following to my previous patch:
