Is there a way to inspect an image (i.e. firmware, either factory or sysupgrade) without having to install it to a router?
The image may be one you have downloaded or created using an image builder.
Inspecting would include:
seeing which packages and config files are in the image
opening and reading a config file
extracting the config files out of the bin file.

One of them best tools for inspecting any binary image in general would be binwalk.
