Hi, Jelmer!

Firstly, thanks for your reply.

I suspect that we already have dependency hell in Samba4, and my
find_depends command that is attached below will show you this.

That's what I was thinkning about when I was making this patch. And
this patch is good platform for this. However separating everything so
we don't have circullar dependencies is a huge janitor job that
requires writing a policy for a whole project.

The initial separation (libtorture and libsmb) was done that way
because that libsmb and torture are easily separated.

Yup, I've noticed that.

I prefer that builder should have a choice in almost everything
including build types. If he wants shared we give him shared, if he
wants static, we give static, because there can be a lot of
applicances for samba where different builds are needed. 

hej do,
