Probably the applications' defaults. Please keep in mind that utmp
-- very simplified -- is just a file and a simple API. Applications
_must_ write to it, the system does NOT take that action. There are
no logging options to utmp.

As time went by, since the initial utmp, less and less applications
wrote entries -- and some of them made it optional, some of them
just dropped support.

*Usually*, but not always, an entry is written if you set the
application default to "simulate login" (or whatever it is called,
varies a bit); this is mostly valid on terminal emulators or shells.

So. Chances are the applications changed the default for utmp.
Certainly *nothing* in utmp would do it.

Hope it helps,
