Thomas,
sorry for the huge late of this reply.
Regarding your problem with /dev it's surely a bug and I think the following
patch should resolve. But I don't understand why your /etc/modprobe.conf is
removed. Probably the reason is that it's not in your image, but in this case
how is it generated? by a /etc/init.d script?
The workaround is to add /etc/modprobe.conf in
/etc/systemimager/updateclient.local.exclude, so that it'll be excluded by all
the si_updateclient operations, but this is a workaround and not the solution.
Someone knows or has some details on how /etc/modprobe.conf is generated in
RHEL5???
Thanks,
-Andrea
