Yes, this would be great.  It should probably only do this for files in
SCCS and BitKeeper directories, because vim (for example) will do the
wrong thing with hard-linked files if you edit them.  Maybe there could
be another option which would relink all of the checked-out files as well,
for people who use emacs?

One thing that I've noticed (got my first linux-2.5 clone last night) is
that the kernel build process is somewhat broken by the fact that not
everything that you need to build is checked out of the repository by
make.

It appears to handle .c files ok, but it failed for all of the .h files.
I take it this means that gcc doesn't know anything about SCCS, and it
would also appear that make is not properly checking dependencies for
these files, or it would have checked them out, right?

Also, things like "make menuconfig" and such also fail (because they are
doing stuff within scripts that have no concept of SCCS or BK).  Will
the new kernel build system take any of this into account?

I would prefer if we only checked out as much as we need (instead of
doing something like 'bk -r edit' which will use up a lot of space in
each clone for architectures and drivers which I don't need).

Cheers, Andreas
