Thanks. He meant this patch: http://lists.infradead.org/pipermail/barebox/2012-September/thread.html#9304 Reading this discussion again I still have mostly the same opinion: an /env/boot/* script should be simple, it should be adjustable. We should resolve this now. So Jean-Christophe, What you want is to boot your board with informations provided by the dhcp server. Looking again at your patch back then the following should do it: /env/boot/bootp: | #!/bin/sh | | path="/mnt/tftp" | | ifup eth0 | | # Set variables based on information provided by the dhcp request | nfsroot="${global.dhcp.rootpath}" | global.bootm.image="${path}/${global.dhcp.bootfile}" | global.bootm.oftree="${path}/${global.dhcp.oftree_file}" | | bootargs-ip | global.linux.bootargs.dyn.root="root=/dev/nfs nfsroot=$nfsroot,v3,tcp" Since you reject changes to the default boot source for this board your other issue seems to be that you want your board to execute this bootscript without further adjusting the environment. This is something we cannot do. The default bootsource can only ever fit your personal or someone elses use. We cannot make everyone happy with the default boot source, so I suggest you either control your board via some expect script (which sucks, I know) or you just save your adjusted environment on your test board.
