Hi Arnav,

As part of GSoC last summer, Theodore did a lot of work adding
missing compat-linux system calls. I am not sure if there are many
popular ones missing. The way to find out is to install the latest
NetBSD version (10 or current) and then install a very recent compat
linux package (from pkgsrc, perhaps even getting a newer one to
work that is there already) and see how many binaries work, and
from the ones that fail, which system calls they need.


Best,

christos
