Today, I apt-got newest telnet(d), and saw that the behaviour is indeed
like in the original report, i.e. xinetd.conf says:

service telnet
{
        flags       = REUSE NAMEINARGS
        socket_type = stream
        protocol    = tcp
        wait        = no
        user        = telnetd
        group       = telnetd
        server      = /usr/sbin/tcpd
        server_args = /usr/sbin/in.telnetd
}

And still, telnetd does:

open("/var/run/utmp", O_RDWR)           = -1 EACCES (Permission denied)

I'm terribly sorry for the FUD, but the submitter really said that it
works (and I blindly believed him... hmpf :( ).

I'll inform the upstream author, Rob Braun, so we can get this fixed.
