I still make development images when I get some time but those versus a tested for general audience release requires more time. I have a omniOS and omniOS CE release. They require more testing and different matching pkgsrc release, dropbox mapping. I'll see what I can do for you with the omniOS release.
The path to ubuntu zfs is an option but you will need to make some changes. The cifs server is smaba and you would have to adapt administration to config file. Same for NFS. You'd have to run from a hd install and I'm not sure if the hd or mobo dies if it will transfer seamlessly to new hd. Just some things to consider and test before comitting to the leap with your data. Hope that helps.
