@elip - Yep. Linux is great until your company decides to dump HP-UX for it to save money and you are responsible for production system up time (so far so good for me arguing but some others I work with not so lucky). Never seen HP-UX kernel panic ever. Had a Linux system crash this week (get your move fast and break things the fsck out of here). Vendor having control of both hardware and software tends to make systems expensive but you generally get what you pay for.
