I'm glad you have such good network access. I do not. A lot of the
world does not.
If you want to add in functionality to upload files I won't to
block it - but I do not want that at the cost of removing remote file
downloads. If you lobby to remove remote file downloads on builders
you're going to be creating a lot of problems for yourself.
Please don't make us start having to get approval on individual patches.

B/c it makes sense - b/c it cleanly separates the FE and BE?

And yet it means we have to be able to house and cope with those on the
frontend and write them out. I'd really rather them not ever be there
specificaly for the security and integrity of our own systems.

We have a about 400GB allocated right now and we could probably add
another 600GB before we need to look for more space for cinder volume
So let's call it about 1tb at the moment.

Actually I mean on the private cloud security groups level.
Iptables on the builder would be meaningless - anyone who can install a
package into the chroot is effectively root. rpm pkgs are installed as
root and any root user can walk out of a chroot - counting on iptables
on the buildsystem is unsafe - we'd need to do it with security groups
in the cloud system.

Please don't. You'd be much more help just by helping rather than
making me and others defend decisions and plans we made before.

I'd rather we work on the specific items that are left to do, get this
available to all fedora packagers and adapt as we need to.

COPR IS FOR ANY PACKAGE NO MATTER THE QUALITY.
I put that in caps to make sure it was not misssed.
It is absolutely mandatory that we are not imposing packaging policies
or rules on anything that goes in coprs.
Exceptions to this rule include:
1. packages which cannot build (by default of course)
2. packages which are not legal to be build ie: don't have a
valid/acceptable license tag.
otherwise ANYTHING goes.

Sure - provided we have it.

Let a thousand flowers bloom and we'll pick the best ones later. The
crap gets mowed under for compost.
