I know of Arista (and the rest) all too well.

It still doesn't change the fact that putting all eggs to one penguin-shaped basket give me the heebie-jeebies. Monoculturization is never a good thing, yet everyone seems to run towards it with a glee on linux.

At least I can put money where my mouth is and continue budgeting for Juniper as long as they support FreeBSD.
