Re: [PATCH] isar-installer: run installer under agetty and reboot via EXIT trap

["'Heinisch, Alexander' via isar-users" <isar-users@googlegroups.com>]

I doubt this patch can be applied onto next.

On next deploy-image-service already got replaced by target-
bootstraper-service - Still, the invocation is similar.

https://github.com/ilbers/isar/tree/next/meta-isar/recipes-installer/target-bootstrapper-service
