HOWTO blade

Taken from old HOWTO blade. This page might be outdated.
Short description on how to make blade servers use a readonly nfs root filesystem. nfsroot is in apemaster{n}:/apeboot/{distribution} currently distribution="sl3.0.5_ro" In an early stage rc.sysconfig calls rc.ape to set up a ram filesystem where files are copied which hold hostspecific configurations and for write-needing data (like /var/run ...) hostname and ips for server and the host itself are taken from /proc/cmdline and by 'grep'-ping through the file /etc/apehost.conf (created autmatically from hostsystem.xml) kernel configuration can be found in /afs/ifh.de/group/ape/anext/unitkernels specific changes that have been made for sl3.0.5:

• added /apeboot/template directory
• added /ram directory
• source rc.ape in rc.sysconfig
• commented out remount / rw in rc.sysinit
• make many files in /etc a symlink to /ram/etc (which are the files copied in rc.ape from template)
• same for some /var entries
• removed in /etc/rc3.d/: xinetd, gpm
• added in /etc/rc3.d/: S55sshd, S70ntpd, S99local
• made /dev/log a symlink to /ram/dev/log, add '-p /ram/dev/log' to 'SYSLOGD_OPTIONS' in /etc/sysconfig/syslog
• changed /etc/ntp.conf: 'driftfile /ram/var/lib/ntp/ntp.drift' and added servers
• made /etc/mtab a symlink to /proc/mounts
• authorized_keys2 from apemaster copied to /root/.ssh/
