wifi and wpa_supplicant

[CeDeROM]

Hello :-)

I am wondering how exactly the wifi interface and wpa_supplicant is
organized - is there any script at wlan0 interface up that starts
wpa_supplicant for that interface? Do I have to start wpa_supplicant
by hand any time I bring interface down and up (it looks yes for me)?
I have ifconfig_wlan0="WPA DHCP" set in rc.conf so I guess after/when
interface is up both wpa_supplicant and dhclient should be started..?
What should I make to wpa_supplicant starts automatically when I bring
wlan0 up? I am using iwn intel wifi driver.

Any hints appreciated :-)
