packaging: periodically check if ovirt-engine upgrade available
Using yum API and version lock plugin disabled check if there is a newer
version of ovirt-engine package.
If there is, create a trigger file at:
/var/cache/ovirt-engine/engine-upgrade.available
It is the responsibility of the engine to monitor this trigger and clean
when act upon.
COMPONENTS
engine-upgrade-check.py
A simple utility to check if update is available.
It will echo AVAILABLE if it finds update.
engine-upgrade-check.cron
cron.d script to be executed daily. Uses
engine-upgrade-check.py to detect update and creates the
trigger.
