[OpenWrt-Devel] Question Re: Sourceful SDK

[Daniel Dickinson]

Also, I'm thinking that for the SDK sources it might make sense to only 
include packages with an InstallDev section and the toolchain and do 
some work to make sure that packages built as part of the base system 
can't have their config options overridden (at least for an already 
included flavour), in order to guarantee that the compilation produces 
identical libraries and such.

Regards,

Daniel
