I replied to this one by email, but to avoid just deleting the message…Many userspace packages are from squeeze, but many other are not, including the kernel (3.13 now), iproute2, iptables and so on. Not sure about P-01, but if drivers for some widely used hardware are missing, feel free to file an enhancement request. OS/VX looks abandoned to me, last source updates were in June, so it lacks any bugfixes and enhancements made in VyOS since then.
