Cool! I'd say it works the same way on my Indigo R3K:
```
>> printenv
netaddr=172.16.2.103
dbaud=9600
rbaud=1200
bootfile=bootp():
bootmode=c
console=d
volume=128
path=bootp()
cpufreq=33
diskless=1

>> boot
Setting $netaddr to 172.16.2.103 (from server )

Not sure about that. Because when I try to start with just `boot 
dksc(0,1,8)irisboot` I get the same as when I first started my Indigo 
R3K today and it started to boot automatically: i.e. "Invalid argument":
```
                             Starting the system...

               To perform system maintenance instead, press <Esc>

Invalid argument
i.e., dksc(X,Y,8)loader dksc(X,Y,0)/kern
```

And checking the PROM monitor environment:
```
>> printenv
netaddr=192.0.2.1
dbaud=9600
rbaud=1200
bootfile=dksc(0,1,8)irisboot
bootmode=c
console=d
diskless=0
volume=128
path=dksc(0,1,8)
cpufreq=33
```
...so a default seems to be not used in this case, or the PROM monitor 
supplies a "hidden" argument automatically in such cases.

BTW, `boot dksc(0,1,0)/netbsd` with the above PROM monitor environment 
seems to work the same way as `boot -f dksc(0,1,8)irisboot 
dksc(0,1,0)/netbsd` and first boots the loader which then loads and 
starts the kernel:
```
>> boot dksc(0,1,0)/netbsd
