It's a change, but the meaning of the files that are present in /etc/
won't change. It's only that some more dynamic and volatile files are
moved away.

The spirit of this idea is already in our FHS. In a lot of cases, its
guidelines are already a lot more detailed than those of the commercial
unix vendors.

Other than that, I think it's safe to say currently that the Free / Open
*nixes have become the leading innovators in the field of Unix. I don't
think we'll make much progress if we wait till the commercial unixes
come up with solutions with the problems we want to solve -- especially
if that are problems they care little about, because they cater for a
narrower group of users than we do.

There are few operating systems that have such broad targets as Debian;
the goal is to be the Universal Operating system, no less. Indeed, most
Unixes don't run on embedded systems, a lot don't run diskless, most are
unsuitable for laptops or even desktops, and so on.

I think if Debian comes up with a good idea that's applicable to any
Unix, be it Free/Open/NetBSD or the commercial *nixes, it would be a
waste to wait with the implementing it till the others adopt it before
us.

Also, others may not adopt till they have seen a succesful
implementation. Incidentally, this also applies to the FHS.

If you mean other GNU/Linux distributions or the *BSDs, don't hold your
breath. If you mean Debian developers, it seems that a lot of good
progress is being made.

Cheers,


Emile.
