Hi Ross,
Thank you for your help. My build is using a layer which is generating a file in a ROOTFS_POSTPROCESS_COMMAND command. I would like to modify this file as part of the yocto build, but I'd prefer not to modify/fork this layer as it is from a vender.

I'm creating my own layer, which will modify the file created in the vender layer's ROOTFS_POSTPROCESS_COMMAND command. If I use pkg_postinst, then the file will not have been created when pkg_postinst is called, because (as far as i understand) the ROOTFS_POSTPROCESS_COMMAND commands will only be executed after all packages have been installed on the root filesystem image.

Any suggestions on how to proceed?

Regards,

Donal
