Hi,

I cant understand how useful it is = but, in my opinion,=A0Option 3 (with default as 'all') makes more sense. With Opti= on 3 who doesnt want/know this feature will never worry about it.

Hi,

I got a feature request for preventing taking down an interface on
shutdown. I wonder how we should implement this.

Option 1:

=A0set RC_NETDOWN=3Dno in /etc/rc.conf (or /etc/conf.d/networking) will
=A0prevent taking down all the network interface on shutdown. No support =A0for preventing individual interfaces - its all or nothing.


Option 2:

=A0Use a blacklist (eg RC_PREVENT_NETDOWN) of interfaces to not take
=A0down. For example: RC_PREVENT_NETDOWN=3D"eth0 eth3" will take = down eth1
=A0and eth2 but not eth0 and eth3. If set to 'all', all interfaces = will
=A0be kept up and if set to 'none' all interfaces will be taken dow= n.
=A0Deafult would be 'none'.

=A0Alternative variable names are: RC_NET_KEEP_UP


Option 3:

=A0Use a whitelist of interfaces to take down on shutdown. For example
=A0RC_NETDOWN=3D"eth1 eth2" will keep eth0 and eth3 up on shutdow= n. If set
=A0to 'all' then all interfaces will be taken down and if set to &#= 39;none',
=A0all interfaces will be kept up on shutdown. Default would be 'all= 9;.


What do you prefer? They are all very simple to implement.

What are good variable names?
