@dmbaturin, Im with you on the aesthetics, and the readability. In the firewall ruleset example I still feel that the first is easier read than the second. Are we talking hundreds of lines to parse the former vs the latter? It seems like the later, across a whole config would at 10-20 lines if not more depending on the complexity. I for one am interested in seeing as much of the config on one screen, vs needlessly needing to scroll. As for your Q on pfSense, I've had to edit the xml configuration file by hand based on how pfSense sorts VLANs based on their add date vs numerical value.

As an end user, I just keep coming back to the verbosity of the syntax, and the divergence from all the other established command syntax in this space. VyOS doesn't have the following to do it differently, as it adds another barrier to adoption. Its a subtle change, but it has a long reach, especially when luring former vyatta or EdgeOS converts that want to roll-their-own, vs buy MIPS hardware. While I understand it may save coding time in the end, I'm trying to avoid the verbosity that is pfsense, and awall/shorewall. I bet if you asked a room of non-vyos engineers, they would prefer the first syntax with a much higher percentage, but alas I digress.

I like the separation for admin vs view. Its the same reason we have RO and RW in SNMP v2c etc. While I don't yet have hands-on experience with Junos, I specifically like the demarcation of configuration vs show commands. For those that don't like the dual approach, can't the run prefix be used to enable a flatter CLI approach?
