From those I'm wondering what special privileges netlink plugin needs...
on the systems I run it on, it runs as unprivileged user.

For DNS, Ping and IPTables plugins just setting the appropriate
capabilities, e.g. using file based capabilities, does suffice.
For serial I would say adding the right group should do it as well.

At least file based capabilities and unprivileged user does work fine for me
with ping plugin.
