PXE Server
==========
Description
-----------
The `pxe_server` role generates TFTP boot files for PXE booting Rocky Linux. It
downloads bootable images and generates kickstart files.
It does not actually configure the TFTP server itself; I use the OPNsense
`tftp` plugin to serve these files. You will also need an HTTP server to serve
the kernel and initrd files (you _can_ serve these over TFTP, but it's very
slow).
Grub
----
You will need to build grub binaries and upload them to `$tftpboot/grub`. You
can generate them on an existing Rocky Linux host.
First, install the required packages:
````bash
dnf install grub2 grub2-pc grub2-efi grub2-pc-modules grub2-efi-x64-modules grub2-efi-aa64-modules
````
Then, generate the images:
````bash
# location of the grub.cfg files within the tftp root
PREFIX=/grub
COMMON_MODULES="normal linux echo http tftp reboot configfile"
# The last arguments are the modules to "statically link" into the grub image...
# the alternative is to put like 50 .mod files in the tftpboot directory.
grub2-mkimage --format=x86_64-efi --output=bootx64.efi -p $PREFIX $COMMON_MODULES efinet bsd
grub2-mkimage --format=arm64-efi --output=bootaa64.efi -p $PREFIX $COMMON_MODULES efinet
grub2-mkimage --format=i386-pc-pxe --output=booti386 -p $PREFIX $COMMON_MODULES pxe bsd
````
