Yes. This is what I was trying to explain. Thanks for clearing this up,

Speaking as an administrator of my own set of freebsd-update-servers, I
would suggest a different path to solve the issue. I am not certain what the
exact path would be, but let me attempt to explain the issues I believe would come
The freebsd-update-server software builds binary updates for distribution
using that are updated using the freebsd-client off of an actual distribution
iso that is built using the standard 'make release' process. So in edition to
modifying the freebsd-update-server code to not build this portion of the
release, or at least not distribute it, the client would need to be aware not
to look for it, as well. You can update the client to use a different method for
updating /etc, however the freebsd-update mirror servers will still be
distributing the files, so you will have either a similar issue, or a new
Using the freebsd-update-software, I am not only able to apply security
patches that are distributed by the security team, but I can also apply
patches to /etc, or any part of the release for that matter, when it comes
to distribution of updates from my updates servers. This is the flexibility
I enjoy, and celebrate, in using FreeBSD.
All of this being said, if an update software, and respective client were created
specifically for /etc, it would be great to have similar functionality, in
building off of a distributed iso, with the possibility of patching
available, so this functionality is not lost. In addition to this, also
using keyprints to authenticate the client, and distribute in a similar
I am copying Colin on this, in case he has any thoughts on the matter, or
ideas that may make this a possibility.

This would be great, if you can have it build and work off of a distributed
iso. It would be very disappointing to be restricted to an svn/cvs
tag/branch from FreeBSD, without the flexibility that is possible now using
the freebsd-update-server software. This flexibility allows me to distribute
binary updates for a custom kernel, and to modify /etc and distribute it at

Thanks, and would enjoy being in on any future development thoughts, or
ideas regarding your work on this.
