About Adam Young

I had this in another post, but I think it is worth its own.

echo $address `hostname` | sudo tee -a /etc/hosts
sudo yum -y install ipa-server-dns
export P=FreIPA4All
ipa-server-install -U -r `hostname -d|tr "[a-z]" "[A-Z]"` -p $P -a $P --setup-dns `awk '/^name/ {print "--forwarder",$2}' /etc/resolv.conf`

I call it clear_os_env
