links and copies (was Re: linux-ipsec: Latest snapshot...)

Trouble is, we can't hard-link a directory -- it would mean hard-linking each and every file. And it won't work at all if there's a filesystem boundary in between, because hard links can't cross those boundaries.

I suppose we could *symlink* all the source files. (Kernel net/ipsec is a real directory, but populated only with .o files and symlinks to source files.) That lets "make clean" work properly, and there's still only one copy of the actual sources. Hmm. This has merit.

Either of these will mean having "make insert" add a symlink or two for things like the common library files, because if the kernel net/ipsec is a real directory, then we can't reach stuff in the rest of the FreeS/WAN distribution by just going ../../.. etc.
