[OmniOS-discuss] Fix for no UUID in Kayak-installed BE?

[Dan McDonald]

Given the "uuidgen" binary has WAY too many libraries, and the uniqueness of the UUID doesn't need to be super-special for the installed BE, I put together this patch using the existing miniroot tools:


diff --git a/install_help.sh b/install_help.sh

I initially tested by invoking the prtconf & echo commands, to make sure the resultant UUID looked correct.  I am spinning a bloody ISO as I type this to try and make sure it ACTUALLY works.

Thanks,
Dan
