There are two ways to look at this. First, is FreeBSD eligible to use the UNIX trademark? No, we haven't put forth the thousands of dollars required to get approval from the Open Group. Second, does FreeBSD have a UNIX pedigree? Yes! FreeBSD is a direct descendent of 4.4BSD, a real UNIX. It may not be a "real" UNIX, but it is much closer to UNIX than any Linux ever will be. If you want a Free and Open Source operating system that's as close to "real" UNIX as possible, the BSD's are the way to go. > Second, what type of file system does it use? Does it have a journaling one > like ext3? Do UNIX systems require any kind of defrag? FreeBSD uses the UFS file system. It is a part of the operating system, and not a third party module like ext2/3, reiserfs, xfs, etc. It doesn't have a defrag, because it doesn't need one (neither do any of the Linux filesystems). As to journaling file systems, you need to ask yourself "do I need one?" A genuine purebred JFS is something the average user does not need.FreeBSD uses a different system called "softupdates", which does most of what you want with a JFS anyway. > I have also read that a lot of sysadmins are nervous of putting mission > critical apps on a enterprise linux system and prefer to use freebsd. What > is the problem that I'm hearing that linux has? "Mission critical application" is yet another buzzword. It means different things to different people. At some companies the mission critical application is Microsoft Outlook! So let's look at it from a different direction. Which OS would you trust to run your business? I would choose FreeBSD (or maybe NetBSD) over Linux any day. This isn't to say that Linux is bad, it's just that FreeBSD is better. Take a look at the uptimes as reported by NetCraft. Take a look at the number of exploits found for FreeBSD versus Linux. Also take a look at the design. FreeBSD is a single unified operating system with complete documentation. All the parts of the system are part of a the same project, and designed to work together. On the other hand Linux is a disparate collection of parts built by separate projects, and shoehorned together by a bunch of distributions. > I look forward to your reply. Thanks Don't trust me, trust yourself. Install and use FreeBSD for an extended period of time. It won't cost you a dime, and even if you end up preferring Linux, at least your UNIX education will have a bit more depth.
