rudder-agent installation may hang infinitely on Centos minimal install due to curl installation

Description
I tried to install rudder-agent 3.0beta2 on a centos6 but the install hangs forever ( waited for 15min, Nicolas waited for 2 hours on his side)
It happens that i used a centos minimal install with no curl installed.
It hangs on cf-agent run, because it tries to install curl using yum. but since we are already installing rudder-agent with yum (locking yum), cf-agent is blocked by its yum (yum check-update)...
We should not install curl in initial promises, but instead use the bundled minicurl script

Hm... I feel that the best solution to this would simply be not to execute cf-agent / check-rudder-agent during any pre/post install script.
The only occurence I found of this has been introduced by http://www.rudder-project.org/redmine/projects/packages/repository/revisions/3d74cf3fb5bf4c0b5a38e8cb566905315780ff8b

Actually, I think just removing those would solve the issue, but I'm not certain why they were put here in the first place. May someone explain it to me please ?
Suggestion:
nohup /opt/rudder/bin/check-rudder-agent >/dev/null 2>/dev/null &

Yes. The point was to generate a UUID for the machine. Many things won't work without a UUID (like inventory...). If the user does this, it will break:
- yum install rudder-agent
- servicer rudder-agent start
(because there is no UUID, because the agent doesn't create it, but the check-rudder-agent script does)
