1. I can see what this patch mainly does is ensuring groups first, then user, then groupmems. But the current useradd_preinst, which is called by useradd_sysroot has already ensured this. Is that not working?

2. You're using bb.warn as a method of outputting debugging information, which I don't think is appropriate.

Qi

postinst-useradd-* haven't been running in order of dependency.

This patch is reworked from Piotr Łobacz's patch and fixes:

https://bugzilla.yoctoproject.org/show_bug.cgi?id=15084
https://bugzilla.yoctoproject.org/show_bug.cgi?id=13904

It ensures that groups, users and groupmems are all run in the correct order.
