dhclient conflict between /sbin/devd and /etc/rc.d/netif ?

[Robert Jenssen]

Hi,

Thanks for the prompt reply. By "owned", I meant that "ps -ajx" 
shows /sbin/devd as the process group leader. For example, at the moment on 
my system:

[root etc]ps -axj | grep devd
root        5727     1  5727  5727    0 Is    ??    0:00.00 /sbin/devd
[root etc]ps -axj | grep dhclient
root        6373     1  5727  5727    0 I     ??    0:00.00 dhclient: ral0
_dhcp       6395     1  6395  6395    0 Ss    ??    0:00.09 dhclient: ral0
[root etc]             

I agree, /sbin/devd calls /etc/rc.d/dhclient which checks for the existence of 
a running dhclient. I find the rc scripts hard to follow but so far as I can 
see /etc/rc.d/netif simply calls "ifconfig dhcp" and doesn't check for a 
running dhclient. Here are the relevant lines in my rc.conf:

rc_debug="YES"
ifconfig_ral0="inet dhcp channel 10 wpa up"
devd_enable="YES"

Here is the output of "/etc/rc.d/netif restart":

Now I have four dhclient processes:

[root etc]ps -axj | grep dhclient
root        9824     1  5727  5727    0 S     ??    0:00.00 dhclient: ral0 
[pri
_dhcp       9853     1  9853  9853    0 Ss    ??    0:00.00 dhclient: ral0 
(dhc
_dhcp       9880     1  9880  9880    0 Ss    ??    0:00.00 dhclient: ral0 
(dhc
root        9826     1  9283  1916    0 S     p0    0:00.00 dhclient: ral0 
[pri

It seems that devd has started two new dhclients and netif has started its own 
pair as well. 1916 is the process id of the bash shell I su'ed from to 
start /etc/rc.d/netif.

Best regards,
