Following up on this patch, attached is a modified version of this
patch, to use ${root} as appropriate.
I added this because running the tests on a SPARC machine with LDoms
caused other tests to fail.
I've not added any tests for LDoms itself since I didn't think it good to
add a character device to be added to the git repo.
Thanks,
Darren.
