Is cloning pfSense a good idea?

[hannes.hutmacher]

Hello,

actually, I install the pfSense from a USB stick. However, I have 50 firewalls to roll out that I would like to pre-install. So I think I can clone it. The pfSenses will be linked later using openvpn. Are there any pitfalls that I should consider when I want to operate cloned devices? Do I have any disadvantages later?

The copy you downloaded from here can be installed an infinite number of times.

@hannes-hutmacher I think will be better if you save your config to xml file and then make fresh install including xml import option.
