In that case, you need to put it on the miniroot. :-)

Yeah, uuidgen is the right way to do this, and since 014 is the earliest 
supported release, you're insured of success.

FWIW, since https://www.illumos.org/issues/4769 integrated we have
/usr/bin/uuidgen.  All currently-supported OmniOS releases should have
that (I know 014 does).

Some nice people put a bash-only version of a UUID generator up on

Sorry about the diff; my github-fu is currently zero.  Also sorry
about fixing the ancient typo in RunInstall; could not resist.

I can't test this until I have a new box to install; feel free to play
with it or ignore me until I follow up with a "confirmed working" mail.

Yes, the install_help.sh is definitely where it should go.  I think it
should be in the BuildBE() shell function somewhere after the "zfs set
mountpoint" line.  I'll try to come up with something.

Yes, building those properties into the image would be bad. I'd say
the proper thing would be to either add the necessary commands to the
ApplyChanges function [1] or make a new function and have it run
before MakeBootable.

I'm also trying to get LX up and running on OmniOS.  I'll have some status for 
the list today, but there's still a lot of work to be done.

But wouldn't that mean that all instances installed via Kayak have
the same uuid?  Not sure I like that... IMHO this should rather go
into the actual client installation process somewhere.

I have a workaround, so there's no rush.  Have a good vacation!
We can continue the discussion when you're back.

The creation of the Kayak ZFS send stream probably needs to set these 
properties.  Looking around here:

https://github.com/omniti-labs/kayak/blob/master/build_zfs_send.sh#L68

that seems the natural place to do it.  If you're feeling ambitious, you can 
fix this script and see if you can build your own Kayak send stream.  We do 
consider pull requests in any omniti-labs repo for OmniOS (illumos-omnios, 
omnios-build, pkg5, kayak).

I'm not able to fix it today, and I'm on vacation starting COB today.  After I 
get back, I can probably respin media with a fixed version of this in place.
