how to export multiple different image

[qinghon]

I'm trying to use debos to build an image similar to armbian, and need to image many different devices.
Most of these images only differ in devicetree/uboot

The current debos example only uses one yaml file to implement a single image export, and the action execution results are superimposed.

Is there a way for debos to make multiple slightly different images and export them?

I'd suggest to create two recipes; one which generates a generic tarball (with the pack action); then a separate recipe which generates the hardware-specific image.

YES! , This can solve a lot of problems
According to this idea, the steps should be

step1：

debootstrap
any action
pack

step2:

unpack
any different action
deploy

But it may not be very flexible, for example:

• Only two layers are supported. If a batch of hardware is not very different and is divided into multiple groups, the same group will have many repeated actions.
• Redundant pack/unpack steps

I think the ideal process in this scenario is:

debootstrap
any action
commit0
fork commit0
another action
commit1
fork commit1
another action
export image0
fork commit0
another action
export image1

Enter multiple yaml configurations from the command line and generate an execution tree, and finally export all leaf nodes.

Maybe I should fork the repository and write a demo

BTW, I am making an image for a box based on amlogic CPU. Amlogic cpu types are not too many, but there are many boxes derived from it, most of which have duplicate configurations.
