I'll just toss a few more (both Linux and non-Linux) datapoints in there, based on my own experiences and what I've seen in others. Going from Slackware to commercial UNIX or BSD is easy, but somebody who's only used Red Hat or Debian will feel much more pain (less with Debian, though, and a lot less if he knows both). Going from Slackware to Red Hat is easy but filled with frustration. No matter how good natured somebody is he'll be swearing like a sailor the 3rd or 4th time he has to recursively grep every file under /etc to find where they buried the setting for some normally-easy change. Debian has a similar problem, but not nearly as bad - like somebody else said, it's sort of a middle ground. The same would probably apply to moving from commercial UNIX or BSD to RH or Debian. Somebody who's only used Red Hat can not be trusted to run any other type of UNIX, and can probably only be marginally trusted to run Linux systems that aren't loosely based on RH. A number of the "Linux administrators" I've dealt with who only knew RH were the rough analog to the Windows NT admins who don't know any of the underlying mechanics of NT, PC hardware, or networking, but know how to drive a mouse. Somebody who only knows Linux needs to be very, very careful when dealing with commercial UNIX. A lot of Linux stuff tends to be very BSD-ish, and pretty much the entire commercial world is System V. I've seen and heard of Linux people doing amazingly stupid things that are actually not completely stupid because that's how you do it on a Linux machine - they just lacked the experience to know better. If you want to concentrate on Linux and ignore the rest of the UNIX world, learn Red Hat plus at least one non-RH-based distribution. RH is popular because it's got a company behind it, so companies like IBM certify their products on RH and managers love that magic word "certified". And to hell with all the bugs. Knowing some other system will mean that when RH's tools totally mangle your config files you can figure out how to fix them (or if RH blows up in some new and interesting way, etc.). -- Michael Heironimus -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
