[yocto] Modify RFS before final image is created

[Tobias Blom]

Hi all,

I’ll answer my own question. It seem ROOTFS_POSTPROCESS_COMMAND or ROOTFS_POSTINSTALL_COMMAND is the way to go.

I did however run into a problem when running my script. Using variable ${D} in my ROOTFS_POSTINSTALL_COMMAND gives the “wrong” path - it points to …/image and I’d expect it to contain the path to …/rootfs. It seem the variable is replaced before my function is executed.

I solved this by using variable ${IMAGE_ROOTFS} instead.
