KBD env variable not working

I just installed QNX 4.25 and Photon 1.13 on a machine. According to the
manual (that is for 1.11) you can set up an environment variable like
KBD=la_CO.num.kbd to configure Photon for a national keyboard.

I have done this successfully on earlier releases where Photon was started
from sysinit with “ph &” at the end. In this release there is a ph.boot
script supplied. At the end of my sysinit for a norwegian user I have put

export KBD=no_NO_102.kbd
ph.boot &

but when photon has started I still have US-keyboard. The file
/usr/photon/keyboards/no_NO_102.kbd exists. What else can go wrong?
