> Ubiquiti's EdgeOS is based on a production major network os, Vyatta, (as is VyOs), and therefor has a lot more scrutiny and bug fixing than those other things
EdgeOS was really based on VyOS... which was based on Vyatta, which was still being used on major production systems even before the brocade acquisition. I have used it in prod myself. I should have said VyOs but still, the point gets across to those not looking to nitpick.
Apparently you’ve not really looked at EdgeOS. https://www.theregister.co.uk/2017/03/16/ubiquiti_networking...
Vyatta was acquired by Brocade in 2012. Ubiquiti forked after that.
