gostwire-1 exited with code 2

I'm guessing this is because NSpid is missing from /proc/<pid>/status in kernel version older than 4.1 (https://man7.org/linux/man-pages/man5/proc.5.html)

my test VM is currently using kernel version 3.10.0

Thus wanted to confirm if there are some minimum requirements as it's not mentioned in the docs.

First, thank you very much for your detailed bug report. And yes, you're correct, we don't support kernels this old. While we in Industry have some long term support, this one is even beyond that window of time. I'll update the documentation accordingly, as you are perfectly right in pointing out we never documented the minimal requirements in several places.
