What about this.

People seem to have problems in a comparison. Seriously and 
indenepndently done, or not.

For interested people like me with a basic education in "modern 
operating systems", I'm, for instance, not familiar with several termini 
technici. Let us start with the scheduling/scheduler. It is always usual 
to use the so called O-calculus ("Big Landau"-Symbol). How about to 
start with just lining up some "commong" things those POSIX operating 
systems do have. Scheduler, their internal "logic" and some pro and contra.
Or "Big/huge pages". As far as I can recall BSDs call them different 
than Linux folks and for those not that deep in OS-internal bits it's 
hard to figure out what's meant to be said by "huge pages". I'm pretty 
sure, OS X has the same - but the child is called by another name. And 
even more, for those not familiar with the history and reasoning of the 
two great UNIX-evolution trees: How init starts up. BSDs/MACH start in 
two steps, SysV/Linux needs seven or so. And even this: what is the main 
difference between OS X (MACH), Linux (SysV based) and FreeBSD (4.4BSD 
based)? I'm pretty sure, all you people reading this list and emails are 
quite able to digg for the right answeres pretty fast since all of you 
are involved in the matter, but try to find answeres beyond your 
knowledge, imagine a perspective of those looking for the holy grale but 
do not even have any idea how the grale looks like! This could be a good 
startting point, being neutral and having still the ability to start 
comparisons if desired.
Like me, I do not know much about the filesystems and capabilities of
those beyond FreeBSD's, so facilities like journaling etc. could be 
mentioned and so on.

What about such a "first step"?

Sorry, if this already has been realized anyhow on the page and I'm 
simply to blind to find it (it would otherwise be a index of "it could 
not be find as easy as it is supposed to be").

Regards,
Oliver
