cobbler-loaders

Cobbler loader files (predating Cobbler 3.2.x), plus lpxelinux.0 (natively supports HTTP and FTP transfers).

Additional packages that need to be installed on CentOS7:

• grub2-pc-modules-2.02-0.87.el7.centos.6.noarch
• grub2-efi-x64-modules-2.02-0.87.el7.centos.6.noarch

yum install grub2-efi-x64-modules
yum install grub2-pc-modules

Used through symbolic links in /var/lib/cobbler/loaders/grub:

i386-pc -> /usr/lib/grub/i386-pc/
x86_64-efi -> /usr/lib/grub/x86_64-efi/

Some older files (before 18 Nov 2012) can be found here for reference or comparison: https://dgoodwin.fedorapeople.org/loaders/
