Installation

This section describes the various installation methods, e.g. PXE.

PXE Server

The PXE server is pxeserv01.psi.ch, running SL 5.1.

Directory structure

The usual /tftpboot/pxelinux.cfg setup. The pxelinux.cfg directory contains the following subdirectories:

Boot: could be Windows-related
centos: CentOS 7.0, 7.1, and 7.2
dl: diskless systems
pxelinux.cfg: PXELINUX configuration
scientific: Scientific Linux, 3.01 -> 7.0, partly obsolete
tools:

PXELINUX

The PXELINUX configuration files are in pxeserv01:/tftpboot.

The default file currently contains 127 labels.

Scientific Linux 6, 64bit

One thing to note is that the [Kickstart file](http://linux.web.psi.ch/kickstart/configs/sl64-64-desk-stable-ks.cfg) is modified during installation by the [ks_pre.sh](http://linux.web.psi.ch/dist/scientific/64/kickstart/bin/ks_pre.sh) script.

Kickstart

The documentation on Kickstart files is currently based on sl64-64-desk-stable-ks.cfg, the default Kickstart file for SL6.

In the %pre section a distribution-specific script ks_pre.sh is downloaded and executed. Errors are not handled. The script modifies the Kickstart file. The latter contains markers #BEGIN_MAIN and #END_MAIN to mark the region to be modified.

Custom keys

The Kickstart files defines variables INIT_KEYS and APPEND_KEYS and exports them for use by ks_pre.sh. The latter attempts to download an environment file and a script custom_pre.sh for each key and sources them.

The custom key related files are stored below /afs/psi.ch/software/linux/dist/scientific/$OSVERSION/custom/. Examples for custom keys are DesktopTesting and DesktopStable.
