>Environment:

FreeBSD 4.1-STABLE workstation configured an an NIS client.
The /etc/master.password file contains only one entry:

	+:::::::::

The file /etc/group contains only one entry:

	+:*::

>Description:

Workstations takes a very long time to bood due to NIS timeout.

The /etc/rc boot script has the following line:

	chown root:wheel /dev/tty[pqrsPQRS]*

This statement occurs before NIS services are started (network_pass2).
Because of this, the system will pause for a very long time at boot
while it attempts to get the UID/GID from NIS until it times out.

>How-To-Repeat:

Setup a workstation to act as an NIS client.

Install /etc/master.passwd with the following line only:

	+:::::::::

Install /etc/group with the following line only:

	+:*::

Reboot the system.

>Fix:

This problem is fixed by moving the 'chown' statement (as described above
in /etc/rc) directly after NIS service startup (network_pass2). This
allows the chown statement to properly get the UID/GID information it
requires from NIS hence avoiding the timeout.

This is wrong. You should always have a root entry in your passwd
file, even if you're using NIS.

This is also wrong; you should always have a wheel entry in your group
file, even if you're using NIS.
