I've been thinking about this more, and I'd like to wave a thought at people: I propose for consideration the idea that pseudo have a compile-time hard-coded default answer to "what is uid 0" and "what is gid 0", and use that instead of the "fallback path". The rationale is basically: Yes, it's a special case. But it's *the* special case. It's the special case that is the uid pseudo emulates by default, and it's the only one that most packages ever need. If we do this, then the only packages which need to depend on base-passwd are those which need to actually use a *non-root* uid/gid. And every such package had better already have a dependency either directly on the passwd stuff, or on some other package which does. I am pretty sure that this makes more sense than the default fallback to host passwd/group. I might want to preserve the option of that fallback, but make it a non-default. Anyone have strong feelings on this? Thoughts I may not have thought through yet? I don't know that I actually had a coherent reason in mind for the original fallback behavior, and this analysis convinces me that falling back to host uid/gid is probably wrong for many-to-most use cases. I guess it might make sense for something more like a debian package build where you really are targeting the host, but even then, I am not sure that the default host fallback is a good idea. -s -- Listen, get this. Nobody with a good compiler needs to be justified. -- _______________________________________________ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.openembedded.org/mailman/listinfo/openembedded-core
