Indeed, but its output should be shown in review and commented. This
hasn't been done for binary packages.

Is there an url for that patch?

a variable is set but the value is never used??

Ok. This patch seems clean to me. However I am not convinced that
having the script created by the patch is the best approach. Isn't
that script provided on the net? Shouldn't it be a Source instead?
It is not a blocker but a suggestioon.

And about merging them?

In my opinion the patchset is not acceptable as is -- even though
I believe you when you say that it was worse before and it is now
manageable. All the changes I ask and you agreed upon are required,
in my opinion, in order to make those patches easier to understand
and review. So to me it is a must fix. Still I understand 
perfectly that this issue may be low priority for you and I guess
you have enough work already. But I wouldn't let such a patchset
enters former fedora extras so it is the same here. However there
is no need to hurry, there is has never been a time constraint on
fedora review, package quality is the most important thing, and
clearly this issue is not easy to solve. So, my opinion is that
you should just leave this as is until you find time to clean things.
The package won't be approved until them, but since it is already
in fedora it is not a big deal. Another possibility would be for 
you to ask some help from the community, I guess that dhcp is a
very popular package, and it could be possible that somebody helps
you to fix that issue.

Indeed, but here the same change is done 5 time in the patch,
there is no nice comment in the spec file to explain where the
flags come from, and RPM_OPT_FLAGS is conveniently used in the 
spec. The end result is the same, but in my opinion it would
be more elegant to change LFLAGS on the command line. I won't
make it a blocker.

That is a blocker (or need an explanation).

Shouldn't it be simpler and less intrusive to %exclude them?

It is in dhcp-devel. I think it shouldn't be shipped, so I ask
why is it shipped?

This renders such changelog entries rather unuseful in fedora. Not
a big deal if things are commented in the spec.

I suggest getting rid of COPTS completely and putting things directly
on the command line.

Why don't you simply ship dhcp-options.5* and dhcp-eval.5* in both
packages?

Part of this explanation should be in a comment near -fvisibility=hidden
along
# -fvisibility=hidden is needed for libdhcp4client, it is the simplest
# way to avoid collisions by hiding everything and exposing only 
# the symbols needed

Mmh, I guess this dependency comes from dhcpd-conf-to-ldap, it is 
still there...

As I expanded above there is no need to rush, but the patch layout
is not acceptable. I really can't see why the requests are unreasonable
for the Core/Extras merge review. To me it is the reverse: letting a 
package which isn't perfect (from the packaging point of view, of 
course ;-) be merged would be unreasonable.

I see. Is there a formal collaboration between linux package distros
maintainers, and also maybe linux and BSD maintainers?
