Yes, that's dirty for now, we probably want something cleaner otherwise
we'll have to carry unconfortable tricks.

You mentioned fsys_getroot at some point. This indeed looks like a
proper way to build a protid with uid=0. That's what
libdiskfs/boot-start.c's diskfs_start_bootstrap does to get access to
the exec server.

Yay!!
