PXE booting for Diskless Controllers

To facilitate the booting and diskless environment for the VME Controllers, these packages were installed onto gluon20:

• dhcp
• tftp-server
• syslinux

All supporting configuration files and diskless environment are found here:

/halldfs1/diskless

with subdirectories:

• CentOS5 - Contains the CentOS 5 operating system that is mounted READONLY (root), as well as "snapshot" directories for individual controllers to provide read/write files for the operating system configuration.
• tftpboot - Contains the directory that is served by the tftp-server
• conf - Configuration files for tftp and dhcp. On gluon20 softlinks are made to these files where they are needed:

/etc/dhcp/dhcpd.conf -> /halldfs1/diskless/conf/dhcpd.conf
/etc/xinetd.d/tftp -> /halldfs1/diskless/conf/tftp
