Seems to me like diskfs_create_node should not set the S_ITRANS or
S_ISPARE bits, but of course, it should set the S_IFMT and permissions

The sticky bit means something quite different between dir-mkfile and
dir-mkdir; on ordinary files, it's privileged.  (Or once was, in BSD,
when it really meant something.)
