r in front of any block device is the raw device for it. It access the data directly on the drive without using the buffer cache. FreeBSD 5.x no longer makes a distinction, and 4.x may still. For swap, I'm not sure how it interacts. Swap may always be raw since the point is to free up some ram and therefore it shouldn't be cached in ram. > > -- > Kjell > > _______________________________________________ > [email protected] mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "[EMAIL PROTECTED]" -- I sense much NT in you.
