If a image uses task-A and task-B at the same time, there would be conflicts, this would be fixed if pkg_c can be removed by task-B, something like: RDEPENDS_task-B -= "pkgc pkgx..." 21081 1 sgw 2012-05-03 23:15:33 +0000 Dependencies are there for a reason, removing a dependency may break other packages. I am not sure that this makes sense 21093 2 liezhi.yang 2012-05-04 02:04:04 +0000 (In reply to comment #1) > Dependencies are there for a reason, removing a dependency may break other > packages. I am not sure that this makes sense Yes, this is a potential error, but the task itself should take care of this, if RDEPENDS_task-A removes a dependency of task-B, then task-A and task-B should be conflict tasks, or there is something else wrong, and the dependency error can be raised by bitbake. This can make task assemble more flexiblely.
