SystemImager is software that automates Linux installs, software
distribution, and production deployment. SystemImager makes it easy to
do installs, software distribution, content or data distribution,
configuration changes, and operating system updates to your network of
Linux machines. You can even update from one Linux release version to
another! It can also be used to ensure safe production deployments.
By saving your current production image before updating to your new
production image, you have a highly reliable contingency mechanism. If
the new production environment is found to be flawed, simply roll-back
to the last production image with a simple update command! Some
typical environments include: Internet server farms, database server
farms, high performance clusters, computer labs, and corporate desktop
environments.
