Time for one of "David's famous simplistic examples" for people to
If, as a programmer, I write a (pseudo)script that says:
mv file1 file2
I want to be pretty sure that 'mv' finished before I'm clearing
the lock. Under FFS (NetBSD) this is guaranteed true, under EXT2FS
(Linux) it is not.
At this point, no matter how bright the application programmer is with
his mail server, he doesn't get underlying safety - (unless he writes
a bunch of Linux specific work-around code) even though he's doing
things the 'right' way.
If you're interested in the details, this book provides a good overview
of the issues.

Sometimes, yes. At a previous job, a ran a couple machines worth of
Quake servers, under NetBSD. (Only Linux binaries available...)
Each machine ran 3-4 servers, and people were amazed at the performance,
and availability - compared to other Quake servers.
(This was at a cable company, lots of people using rate 10000, so they
weren't treating the server lightly.)
