Linux ServerWatch writes about the slow but sure death of UNIX by the onslaught of Linux and customers moving from older proprietary UNIX systems to commercially supported open source enterprise Linux distributions. "Linux does have one killer feature that is driving the switch: lower cost. Many companies are discovering Linux to be extremely attractive from a cost perspective. Take the experience of Sabre, a travel company that replaced Solaris with Red Hat Enterprise Linux (RHEL) running on x86 machines, resulting in lowering costs 90 percent (with a three-fold speed gain to boot). These potential cost savings, which include hardware maintenance costs savings, are not to sniffed at."

RE[3]: UNIX is far from dead

I have never meet an admin worth his salt that can't support multiple Unix/Linux platforms.

There's a difference between being able to support a platform and really knowing how the platform works. I mean I've worked with at least a half dozen different *nix variants in my career, but I wouldn't claim to know the ins and outs of all of them down to the last detail.

They didn't need an Admin to only support that one Unix server, but they did need someone who knew Irix (in this case), and could also help with supporting Linux. Not all Linux admins have experience with Irix. And while it is true that most things are similar enough that a Linux admin could work out many things about Irix (I know I've done it), it's always better to have someone who actually knows what they're doing.

If I had an important Irix server and was hiring an additional sysadmin, I'd choose an experienced Irix admin, who could also help out with running the Linux servers over an experienced Linux admin who could teach himself Irix on the job.
