I would say not installing source is a feature, not a bug. but if some files are legitemately missing then we can add, I think.
I hear you re feature, to a degree it makes sense. net-misc/dahdi is a kernel module, so at the very least I require the ability to include the missing oslec.h (it has no further #include's) - which doesn't form part of the standard linux-headers since it's an internal only header. Is there some dependency that I need to depend on to indicate that I require the actual source including headers? Looking at the kernel-build eclass it seems that it's explicit to only install Makefile* and Kconfig* ... is this good enough to actually build any other kernel modules? In which case, can we possibly include oslec.h into that? Quite happy to hack the dahdi-source to be a little less specific about the full path and add additional -I arguments for the compiler. However, it seems kernel-2 (which controls linux-headers) use the kernel's on make headers_install in order to deal with the stuff that needs to be installed, afaik, this is primarily stuff that userspace needs, not kernel modules. This only affects USE=oslec ... which also requires kernel config to have CONFIG_ECHO set (Which I'm not sure gentoo-kernel has). Looking at the code here, the #include should be fixed up anyway, using a full path here is just wrong on so many levels, but even fixing it up, in the gentoo-kernel case, there is no oslec.h to fix things up to.
Last-rited, please see bug #914477.
