createbootvolfromautonbi.py
A tool to make bootable disk volumes from the output of autonbi. Especially
useful to make bootable disks containing Imagr and the 'SIP-ignoring' kernel,
which allows Imagr to run scripts that affect SIP state, set UAKEL options, and
run the startosinstall component, all of which might otherwise require network
booting from a NetInstall-style nbi.
Imagr (https://github.com/grahamgilbert/imagr) is a nice tool for automating Mac setup workflows. It is/was originally designed to be run from a Netboot volume, especially one created with the AutoNBI tool (https://github.com/bruienne/autonbi/). When run from a Netboot image created this way, Imagr runs as root, and SIP is ignored, enabling Imagr to do many of the needed tasks around setting up a machine for initial use.
But Netboot might not be available in your environment. And the new iMac Pro does not support Netboot. createbootvolfromautonbi.py allows you to create a bootable external drive (USB/Firewire/Thunderbolt) from the output of autonbi, and more specifically, the output of the make nbi Makefile target included with Imagr.
This would allow you to create an external boot drive with Imagr that can do what you can do with Imagr from an AutoNBI image.
Usage
./createbootvolfromautonbi.py --nbi /path/to/Imagr.nbi --volume /Volumes/SomeEmptyExternalHFSPlusVolume
