This procedure should be followed when installing ARM type machines with cobbler. The reason for doing so is since cobbler doesn't support installing using uefi, we will need to create a menuentry in grub.conf with the required settings

 dhcp_next_server: 172.21.0.11
 dhcp_filename: "/pxelinux.0"

And run the dhcp ansible role

Add Menuentry to /var/lib/tftpboot/aarch64/grub.conf with the relevant OS type/version settings that you want to install your machines with

For example:

      menuentry 'Install CentOS 8.3 on confusa' --class red --class gnu-linux --class gnu --class os {
      linux /aarch64/centos8.3/vmlinuz inst.stage2=http://mirror.linux.duke.edu/centos/8.3.2011/BaseOS/aarch64/os/ inst.ks=http://172.21.0.11/cblr/svc/op/ks/profile/Centos-7.9-arm text console=tty0 
      initrd /aarch64/centos8.3/initrd.img

* Sometimes we will need to first install one machine without a kickstart file and then create a new kickstart to fit the installation we want to do for the rest of the machines

* We can add our new kickstart file to /var/lib/cobbler/kickstarts and the set one of the cobbler profile to use it so that we will be able to use it in our installation as we see in the example above

Add the vmlinuz & initrd.img(RHEL Distro's) / linux & initrd.gz(Debian Distro's) to /var/lib/tftpboot/aarch64/os-folder/

Boot to PXE boot, choose the relevant entry you created in Step 2 and finish the installation
