Some scripts that might be of use to macOS admins. Might be related to Munki;
might not.
#### 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.
This provides a way to create a bootable external disk that acts like the Netboot environment used by/needed by Imagr.
This command converts the output of Imagr's `make nbi` into a bootable external USB disk:
`sudo ./createbootvolfromautonbi.py --nbi ~/Desktop/10.13.6_Imagr.nbi --volume /Volumes/ExternalDisk`
#### installinstallmacos.py
This script can create disk images containing macOS Installer applications available via Apple's softwareupdate catalogs.

This script was used to extract the firmware updaters from early High Sierra installers and make a standalone installer package that could be used to upgrade Mac firmware before installing High Sierra via imaging.
This provides a way to create a bootable external disk that acts like the Netboot environment used by/needed by Imagr.
Later High Sierra installer changes have broken this script; since installing High Sierra via imaging is not recommended or supported by Apple and several other alternatives are now available, I don't plan on attempting to fix or upgrade this tool.
This command converts the output of Imagr's `make nbi` into a bootable external USB disk:
`sudo ./createbootvolfromautonbi.py --nbi ~/Desktop/10.13.6_Imagr.nbi --volume /Volumes/ExternalDisk`
