This adds a -native recipe for the shadow utilities.
The custom --root option allows the the following utilities to be

Rather than patching the code for all these utilities, can't you just
wrap them in a call to chroot(8)? That is, make useradd.bbclass do:
eval $PSEUDO chroot ${STAGING_DIR_TARGET} useradd ...
rather than the existing
eval $PSEUDO useradd --root ${STAGING_DIR_TARGET} ...
That's a reasonable suggestion. I haven't tried it yet, but I have found
that pseudo's chroot(2) implementation is not complete. One of the cases
where it does not work is when forking child processes, which breaks the
jail and the child processes are no longer chroot'ed.
My guess is that chroot(8) is going to call chroot(2) and then fork a
child process to run its additional arguments.
cc'ing Mark directly in case he has additional comments or needs to
correct me.
