</span>Best is to simply clone the machine after initial setup then change<br>
what's needed, or backup/restore only files (engine-backup --mode=backup<br>
--scope=files).<br>
<br>
Didn't check, but I do not think they actually need all the certs of<br>
all hosts - that is, that it's not mandatory to keep /etc/pki synced<br>
between them after initial setup. Didn't try that myself.<br>
