Borry to keep spamming you all the time.

But could you help me to find a correct place to "modify" image content (packages installed and not installed) and files and services configured in an "adjusted" way so I would have for example:

 - tuned ssh

 - automatically generated root pass to the one I need

 - Also added proxy config to /etc/yum.conf to certain computes, and other would be used without proxy (maybe extraconfig option?)

 - set up kernel parameters, so I would have console output duplicated to serial connection and to iDRAC serial, so I could see login screen over idrac ssh.

 - and so on.

I believe many of those things can be done over extraconfig, I just do not know options to modify. maybe you can point me like a blind hen into a correct bowl? :)))

Thank you in advance.
