Disk Utility Dmg Failed 107 9

For years I've been deploying Macs by using Disk Utility to image the boot drive from a .dmg file. Aside from having to make a new image every time new hardware comes out it's a very convenient system.
I've run into a problem though. Upon building my first 10.13 system for imaging I found that Disk Utility can't make a disk image from an APFS volume. You don't seem to be able to Restore to another physical disk from APFS either.
Maybe my Google-fu is getting weak but the only think I can find anyone talking about with Disk Utility and APFS is the encryption bug. Has anyone else tried making an image of an APFS formatted Mac? Am I missing something?
Thanks.
(P.S. Yes, I'm using the 10.13 version of Disk Utility, not an older version.)

Disk Utility Dmg Failed 107 9

Sep 25, 2011  Then every time I tried opening the.dmg files it came up with the warning message, Disk failed to mount. Device not configured. The only thing that I have read to do THAT I HAVE NOT DONE is find another Mac that can mount the.dmg file and put that onto a CD to bring to my Mac already mounted. I do not know anyone who has another Mac.
