freebsd-dev/etc/etc.i386/inst1.install
rgrimes f8fef135e5 $rotdelay is now initialized to "-d 0 -n 1" and no longer changed based
upon disk type.  In far more cases than not this is the optimal setting
for any disk drive made after 1990.

This now means all installs will have the disks newfs'ed with either:
newfs -b 8192 -f 1024 -d 0 -n 1
or
newfs -n 4096 -f 512 -d 0 -n 1
depending on what the user chooses for the blocking factor.
