The nfs4id program will either create a new UUID from a random source or derive it from /etc/machine-id, else it returns a UUID that has already been written to /etc/nfs4-id. This small, lightweight tool is suitable for execution by systemd-udev in rules to populate the nfs4 client uniquifier.

Just a nit... naming convention... In the past
we never put the protocol version in the name.
Do a ls tools and utils directory and you
see what I mean....

Would it be a problem to change the name from
nfs4id to nfsid?

Not at all.. and I think there's a lot of room for naming discussions about
the file to store the id too:

Trond sent /etc/nfs4_uuid
Neil suggests /etc/netns/NAME/nfs.conf.d/identity.conf
Ben sent /etc/nfs4-id (to match /etc/machine-id)

Maybe the tool wants an option to specify the file?
