batch/bulk installation

will

Interested to know methods recommended for flashing GrapheneOS onto a batch of devices all at the same time... like 20 of them.

strcat

will onlydadjokes You'll spend most of the time enabling developer options, enabling OEM unlocking and booting to fastboot mode. There's no way to automate that for a batch of devices. You need to approve unlocking and then locking on each device too. Not much to be gained by trying to automate it. It doesn't take that long.

You would likely need to write your own scripting for dealing with this.

You certainly cannot flash devices simultaneously, but yes you can flash them one-by-one semi-automated with a script via CLI method. I don't know how often you'll be doing this, but it can put serious overhead on the USB controller which can degrade it overtime.

You also need to account for seriously buggy operating systems that will cause serious issues with flashing, data corruption, etc (Linux is a common offender)

I also flash dozens of devices. The web installer is fantastic, and restoring from seedvault has worked great so far, but a bulk method of flashing/restoring would be awesome for those of us cranking out devices.
