I'm afraid not. The expansion of symlinks into directories under
/S/Links is the wanted behavior. For a straightforward example of why
this is important, look at /System/Links/Shared/aclocal. The problem
here really is with the kernel modules, not with the rest.

We've been basically doing that until now, but I see that we need a
better, more standardized solution.
Here's some ideas to start with:
1) There should be NO kernel modules under /Programs.
Reason: programs shouldn't be packaged with kernel modules dependent
on the particular kernel version that happened to be running at the
2) A kernel module should be a dependency to a program that needs it
Implementation options: 2.1) add support to lines containing "foo.ko"
in the Dependencies file; 2.2) add a new file KernelModules under
3) We should start a repository of kernel modules for the standard kernels.
Standard kernels = binary images published by Lucas.
4) There should be a way to figure out how to compile a needed kernel
module when you're not using a standard kernel.
Proposal: add a "metadata" file (BuildInformation?) for each module in
the kernel modules repository indicating which recipe built the
module, maybe some more information.
5) Suggested layout for the kernel module repository:
Ok, here are some ideas. What do you people think?
