You are amazing. Keep up the great work. We love you!!

I'll test this out as I have time. I'm very excited for this!

At this time, I will consider PRs, but likely not issues unless they accompany a PR.  If you have LX-for-OmniOS suggestions or issues, please bring them up on the omnios-discuss mailing list.

Input on this mailing list would be appreciated.  Currently, if you change BEs, you may not have an LX zone configured, but its dataset will still be around.  You can use "zoneadm attach" after "zonecfg" if you wish.

I suspect I'm doing something wrong with them (as pfiles(1) shows me no open FDs on /sbin/init), but I will not have time to debug them until July 12th at the earliest.  I will also be mostly away from email during this time as well.
