Hi,

... as you see, not at all like /etc/group (which I had originally thought
too).  This example is grouping hosts for nfs mount permission. If you dig
down, it turns out netgroups are just a way to group hosts, or groups, or
users.  Mostly this comes in handy (for us, anyway) for /etc/exports.

Hope this helps,

Charles
