Hi-
At least for testing purposes, it would be great to be able to
manage a system's NFSv4 domain name from the command line. I'm
frequently asked how to determine a system's NFSv4 domain name,
and I'm forced to answer something like this:
> Linux does not currently have a command line tool for managing
> the system's NFSv4 idmapping domain. Use:
>
> awk '/^Domain/ { print $3 }' < /etc/idmapd.conf
>
> If that fails to find anything, then use `dnsdomainname` . That

This doesn't even get into /proc/keys, or what to do to change
the NFSv4 domainname, or the differences between rpc.idmapd and
the keyring-based idmapper.
Linux now has hostnamectl and other tools to manage a system's
hostname and so on. Solaris has sharectl, which can display and
update the nfs4mapid_domain.
Does it make sense to extend the nfsidmap command to display and
modify the NFSv4 domain name?
