Provisioning of ~4,000 RPMs drops from roughly five to six hours to about one hour by switching package installs to DNF via yum-for-dnf repo (or Ansible’s dnf module) and disabling per-RPM disk sync with LD_PRELOAD no-sync. Systems boot from Satellite/Foreman kickstarts with a minimal base, then Ansible applies the rest; the package phase shrinks to about 30 minutes, followed by configuration tasks, and a reboot safely flushes disks so the risky no-sync step does not corrupt images.
