Indeed, init/mainc::kernel_init() doesn't call prepare_namespace()
(which calls devtmpfs_mount()) if an initramfs with an /init is found.

 Arnout> null::sysinit:/bin/mount -t devtmpfs devtmpfs /dev

Not really - Besides adding a devtmps_mount() call in kernel_init(), but
that's kind of icky as well.
