Something like that. It may be a little easier with darcs than it
sounds, though. If you are starting with a clean tree and good REs
for 'boring' and 'binary' files, you can just do:

 $ darcs add -r *

I think it's also relevent that darcs has simpler account for files that
are tracked and not tracked. Boring and Binary are much more more
intuitive than 'precious', which is not a concept I've ever felt I
needed. 

 From my experience with Arch, 'darcs add -r *' is noticeable faster
than visiting eary file that can use a tagline and adding one. Not to
mention the other 5% that may be binary and need to handled differently
anyway.

You do have to use "darcs mv" to move files, but that is about as easy
to remember as just 'mv', and if you forget, you will get a reminder
when reviewing your changes.

You don't always have to use 'rm' either. From the docs [1]:

"Remove should be called when you want to remove a file from your
project, but don't actually want to delete the file. Otherwise just
delete the file or directory, and darcs will notice that it has been
removed."

It is nice that the behavior is completely consistent, unlike tagline
which doesn't work for binary files.

I understand that it's more portable to Windows. (I don't recall what 
problem Windows has was the leading dot, though).

The Linux kernel definitely stresses darcs now. But, I think having the
kernel available as a darcs repo will challenge the project to step up
to tackle the scalability issues.

darcs get http://www.abridgegame.org/repos/darcs/
