As of OS X 10.4.6 the unix command dump still doesn't work. This is nothing more than pure bullshit. dump is arguably one of the most important utilities known to unix. Why doesn't it work? Because it doesn't understand HFS/HFS+. Why it is still part of the system is beyond me. Take crap out that doesn't work on your native file system. Wonderful... it will work if you have everything formatted UFS, but who cares since running a sys off a disk formatted in UFS creates a load of other problems. Shame on Apple - they don't deserve to make the following claim, "Command-line Environment UNIX users will feel at home in Darwin, the robust BSD environment that underlies Mac OS X..." (apple.com/macosx/features/unix/) This is so damn simple... yet still not fixed six years later...
Key Words: OS X, Mac, dump, cannot, can't, work, Apple, doesn't, broken, does not, can not, sucks
(Why am I making such a big deal? When you rely on dump to do backups in a mixed unix environment, you would think that your most expensive and valuable unix system, OS X, would have a functioning version of a unix tool recommended by most people who are serious about backing up their systems. After days of not understanding why I couldn't get it to work, I finally found mention of why on some website. And, frankly, I don't get it.)
