The config tools all take a netdevice name as their argument. What would it look like then? $ ifconfig $(netdevname 'Embedded NIC 1') repeat for each tool that's called? This is similar to what we proposed with the userspace patch and libnetdevname, so the lookup can happen inside each app, rather than the system admin having to do the translation themselves. That was rejected too... otherwise, it's up to a human to do the translation in their head, which isn't script-friendly. -Matt -- Matt Domsch Technology Strategist Dell | Office of the CTO
