It is the normal behaviour, /etc/rc.d/devfs is a little script that
parse /etc/devfs.conf and according to it and what it find in /dev it
set permissions or create links, it's purely static.
One possibility is to call /etc/rc.d/devfs when a device is attached
in /etc/devd.conf (take a look at devd(8) and devd.conf(5))
For exemple, I have something like this in my /etc/devd.conf :
attach 100 {
device-name "umass[0-9]+" ;
action "/bin/sleep 3; /etc/rc.d/devfs restart" ;
};
"attach" : what kind of event
"100" : as usual, for ordering rules
"device-name ..." : the device concerned
"action ... " : what to do, here I use sleep, because action is called
when the attach event arrives, not when the device node is created.
There maybe a better way, but "it works"=A9 ;)
