Re^4: silo

[peter_easthope@gulfnet.sd64.bc.ca]

Ben, Satadru and anyone else interested,

I've spent several hours studying the man 
pages for silo and silo.conf and some of
the Sun Web pages, and experimenting with 
configurations.

This is the revised silo.conf. (The examples
in the silo.conf manpage pertain to two systems
on one disk whereas this is for two systems
on three disks.)  

timeout=100
read-only
image=/sbus/esp@0,800000/sd@1,0;1/vmlinuz
label=woody
root=/dev/sda1
image=/sbus/esp@0,800000/sd@3,0;1/vmlinuz
label=potato
root=/dev/sdc1

Potato was originally installed on the external 
drive /dev/sdc1 and silo.conf was there.
Subsequently I installed Woody on /dev/sda
and sdb.  Now if sdc is disconnected, SILO 
complains that it can not find silo.conf.
This is reasonable enough but I want to run
the system without the external drive.  The 
silo manpage states "The  program /sbin/silo 
... and into the second  stage  loader  it 
records all the block numbers of second.b and 
the name and location  of  the  configuration
file."  

I decided to try to refresh the second stage 
loader.  Hence started Woody and executed 
"/sbin/silo -C /etc/silo.conf -f".  With sdc 
disconnected the complaint about the missing 
silo.conf persists.

Can anyone mention how silo can be persuaded 
write the fresh loader on sda? 

Thanks,         Peter E.
