PXE booting of machines
Most PCs and servers may use the PXE network booting Preboot_Execution_Environment as a boot device.
Network booting Linux for network installation etc. uses the SYSLINUX and PXELINUX utilities. Read the documentation on these pages to get an understanding of the process.
With PXELINUX the node should boot by DHCP and download (by TFTP) the file
which will subsequently download configuration files from
/tftpboot/pxelinux.cfg/ on the DHCP server.
On EL8 systems install these packages:
dnf install syslinux syslinux-tftpboot
The pxeconfig toolkit written by Bas van der Vlies automates the reinstallation of a node
which is easily performed by configuring the DHCP server using
pxeconfig nodename (select one of the available pxe configuration files)
