People see the shiny rack mountable Apple Servers. And then they make the mistake to buy them. Don’t! They are way to expensive. But the worst is, that they are impossible to administrate: It’s pretty much all different. And then when you spent hours and hours to go through the documentation you just have to realize that what you need is simply not there.
I wanted to change the default umask for a user that creates files on the afp server. Too bad. Not possible.
Using mac laptops since years I get to appreciate that the computer is not getting into the way when I want to do things.
Linux is a bit different, you have to google a bit for what you want to do. But 80% of it is pretty damn easy. OS X is just plain obscure. It really is a waste of time. Nobody should be believe that you actually got a unix box when you buy OS X server. What you get is some perverted BSD box that no sane sysadmin would like to deal with it. Phew.
Just try to use a device under OS X (server or not) if you have any doubts.
