DEPRECATED, WILL LIKELY DELETE This page documents creating a new USNO correlator client OS cluster image with new security RPMS.

Rather than applying patches directly to an existing image the process applies patches to a base version and rebuilds the image, this is to guard against RPMs which rewrite config files in /etc.

All work on the OS should be done on the test usno cluster at the NRAO in Socorro, NM. This way it can be tested before copied to the real USNO cluster in DC.

If editing change the versions in the next lines to the next image version so that the page renders them properly

• Set BASEVERSION = 6.7
• Set OLDVERSION = 6.7.1
• Set NEWVERSION = 6.7.2

Updating Client OS

Create new image

As root on nmpost-serv-1

Setup environment

export CLUSTER=usno-corr
export BASE=6.7
export OSVER=6.7.2

Copy pristine base version to new minor version (uses%NEWVERION% as an example)

cd /opt/services/diskless_boot/
mkdir -p RHEL-${OSVER}/${CLUSTER}
cp -ar RHEL-${BASE}/pristine/usno-corr-root/ RHEL-${OSVER}/${CLUSTER}/root
