Juan you keep telling that devfs update fails to boot. But you do know that current devfs is much less forgiving to existing entries in /dev when it tries to register device node and it already exists? And you do know that our rc.sysinit preloads a large number of nodes?
Have you tried to boot with virgin devfs without these preloaded nodes? I Cc it to people who are responsible for devfsd - we need devfs/devfsd updated together. TIA -andrej
