Re: Booting a Sun 3/60

Solution = kernel level module loader.
Situations like this are why it was made.
Read the docs in /usr/src/linux/Documentation, and the help in the
kernel cfg, and make sure it's compiled in and enabled.
Then, the kernel will load modules (via modprobe and /etc/conf.modules)
whenever a call is going to be made.

I use this to load everything now. configure the netcard, and the
modules get loaded. play an mp3, and the soundcard gets loaded, etc. 
On machines with low ram, just make almost everything (except the
obvious things like ext2, etc.) a module, and let it load em and unload
em itself.
One note though - ip forwarding modules are excluded from this. You'll
need to do insmod ip_masq_icq manually still.
