Greetings,
I have tried using both atacontrol and ccdconfig to create stripes and
mirrors of various sizes, and have found that in all cases, read performance
*decreased*.
Is this typical? I have a Promise controller in another computer running
Windows which sees a considerable performance

Seems my toying with atacontrol caused a reproducable panic. I have a perl

Well, perhaps I'm missing something here, but can't you just tokenize the items
in rc.conf using strtok after opening up the file in your C program?
And char buffer sizes is a problem, you can record where the file pointer is,
do you a strtok on say '=', subtract the new file pointer size with
Oh, and changing a bit of what I said in my previous post, you could instead
just pass the strtok to strlen I think and then rewind your file pointer. This
should save some CPU cycles or at least save code complexity by doing it this
way (in my mind at least).
Anyway, just a couple thoughts.

Only if you parse and evaluate the entire /bin/sh syntax.

This doesn't work. /etc/rc.conf does not export
