devfs doesn't set access rights

[[LoN]Kamikaze]

On my FreeBSD 6-stable (the last build is less then 24hours ago) my
devfs doesn't apply permissions set in /etc/devfs.conf when I attach new
devices. I have to call:
/etc/rc.d/devfs restart
manually for the settings to be applied. This is rather uncomfortable in
some cases (especially with my PDA).

I don't know weather this is the normal behaviour, anyway if it is,
shouldn't devfs be restarted automatically as soon as external devices
(usb, firewire, ir) are attached?
