this is not possible unfortunately As if you use symlink the nfs will not work it was work on defaultenv as it’s use the nfs commande and not FS The nfs command handle symlink;w that why in my patch I had to mount the fs first then remount it if it’s a symlink so today the defaultenv-2 break the bootp support > | > | 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.

When the defaultenv-2 will support bootp I’ll be the first to get rid of the old defaultenv but today I have automatic test system that depends on it to test linux on at91 and others Best Regards, J. _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
