First off, it will break every single script out there that uses those commands, thus causing a worldwide riot. Second, it's not compliant with POSIX, thus we reopen the wound of The Unix Wars. Third, it's not a very good solution. Off the top of my head: 1) What happens to machines that don't have a hostname yet? (during install for example) you can't shut them down? 2) Which hostname? The FQDN, which can be REALLY long in many cases. Or the short name, which can be duplicated (how many web00s do I have in various facilities across the country?) so then doesn't solve the problem. 3) I'm not having the problem you describe, thus you're asking me to type more (possibly a LOT more) to solve a problem I don't have. 4) It breaks every single script out there that uses those commands 5) Tied in with #3, there's a REALLY easy way to fix this for those out there who are having trouble with it. I'm unclear why you find the mechanisms built into the system that allow you to fix this yourself to be inadequate? -- Bill Moran http://www.potentialtech.com
