Changed miniroot   - does not remount root until install runs
Changed netbsd-rd  - added the "route" command
Changed netbsd-gen - turned off ncr5380_debug
Added the "security" distribution

Notes on the new "si" driver:

Note that both kernels provided (netbsd-gen, netbsd-rd)
include the new "si" driver for the Sun SCSI-3 interface,
but all the DMA/interrupt/reselect features of the new
driver are disabled by default.  These new features are
controlled by the "si_options" kernel variable as follows:

    si_options = 0	No DMA, no interrupts (shipped default)
    si_options = 1	DMA with polled completion, no interrupts
    si_options = 3	DMA with interrupt on completion
    si_options = 7	DMA with interrupts, reselect enabled

The driver works well with si_options=3 on most systems, but
with si_options=7 (reselect enabled) there appears to be the
possibility for target reselects to be missed (causes a hang).

Here is how to change the value of si_options permanently:
# gdb -k --write /netbsd
(kgdb) set si_options = 3
(kgdb) quit

In summary:  If you are paranoid or can accept poor performance
from the SCSI subsystem, leave si_options=0.  If you want good
SCSI performance and don't mind running some relatively new code,
use si_options=3.  Note that si_options=1 runs almost all the
same code as with si_options=3 and is really for debugging.

Use of si_options=7 is NOT recommended with this version of the
the driver unless you are working on the "missed reselect" hang.
