The advantge is that it still allows to easily pass common arguments to all scripts, adds the possibility to pass custom args to the different types of scripts (post build, fakeroot, and post image). The drawback is that it could break existing scripts that do iterate over their arguments, in they are not prepared to cope with --. I have no idea how prevalent that usage is; I would think that scripts mostly expects a fixed number of arguments, and refer to them with explicit positional args (${1}, ${2}...), or that they are expecting standard getopt args, like our generic support/scripts/genimage.sh, which would then stop processing stuff when encountering '--'. Or even simpler yet, just pass both: $(EXTRA_ENV) $(s) \ $(TARGET_DIR) \ $(call qstrip,$(BR2_ROOTFS_POST_SCRIPT_ARGS) \ $(call qstrip,$(BR2_ROOTFS_PRE_BUILD_SCRIPT_ARGS)) The reasoning here is even simpler: 1. if people provide scripts that have a scommon set of args, and each type of scripts have special args, that just works: - if args are only positional, scripts have to hardcode that knowledge, so they know how to interpret the positionl args, - if scripts use option parsing, like with getopt, then that also automagically works In both cases, they can decide to pass the common args with the existing BR2_ROOTFS_POST_SCRIPT_ARGS, and the specific args with the new BR2_ROOTFS_PRE_BUILD_SCRIPT_ARGS, or they can decide to ignore he former and ionly use the latter; 2. if people provide scripts that have no common args, then they're back to the situation above, where the set of common args is just empty. So, I think this last, simpler option is the best soltuion. Thoughts? Regards, Yann E.

You only can specify one list of arguments that are passed to several scripts (BR2_ROOTFS_PRE_BUILD_SCRIPT, BR2_ROOTFS_POST_BUILD_SCRIPT, BR2_ROOTFS_POST_FAKEROOT_SCRIPT and BR2_ROOTFS_POST_IMAGE_SCRIPT_ARGS). So you have to be careful that the arguments for these scripts do not collide. To allow specifiying dedicated arguments to each of the script the new config options are introduced. For backward compatibility the value of BR2_ROOTFS_POST_SCRIPT_ARGS is passed to the scripts in case the specific argument values are not present.
