>Description:
The ps program does not show 'co' when programs are running in the console
but it shows 'con' and the man page states:
tt An abbreviation for the pathname of the controlling terminal, if
any. The abbreviation consists of the two letters following
``/dev/tty'', or, for the console, ``co''. This is followed by a
``-'' if the process can no longer reach that controlling termi-
nal (i.e., it has been revoked).
>How-To-Repeat:
Some programs run using the console like squid, but it might also be
recreated by running at getty on the console (change /etc/ttys):
console "/usr/libexec/getty Pc" cons25 on secure
and then logging in using that virtual console ans issuing a ps:
PID TT STAT TIME COMMAND
219 con Is 0:00.24 -tcsh (tcsh)
>Fix:
I am including a patch that corrects the problem. Hey, core team members,
apply this patch or change the code to behave as it is reported by the
man page.
