I have several NW6.5sp4a installs (new hardware) and I noticed that when it
created the SYS pool/volume that the volume is set to 0 (zero) read-ahead
blocks. When I looked at some of my other servers that were upgrades from
older versions of NetWare, the NSS SYS volume is set to the standard 2
read-ahead blocks.

Is the zero read-ahead setting for SYS "correct" (normal recommended
default) for 6.5sp4a, or is this a bug and I should increase it to the
normal 2 block read-ahead?
