Hi everybody

I have a rload.lrp package available for testing purposes. All it requires 
it that your network adapters are set up and routing works. This is done by 
moving the modules for your network cards to /boot/lib/modules and declare 
them in /boor/etc/modules.
Additionally you will have to modify the RCDLINKS parameter in 
/etc/init.d/modutils (just in case you are loading modules.lrp too).
The modified parameter looks like:

RCDLINKS="S,S20 3,S15"

Now all you have to add are some parameters in /etc/lrp.conf, add rload to 
syslinux.cfg or lrpkg.cfg and you are done. Here is an example using wget 
to download the additional packages. Originally I used scp but this is just 
a bit too big to fit on a small floppy.

Of course you need a server located somewhere which hold your packages. You 
can use my modified backup script to upload your customised packages or 
just any other copy method.

Here is a brief description how rload works.

By installing the package the rload script gets installed in /etc/inid.d 
and a link gets created in /etc/rc2.d. This script runs at position 15 in 
init level 2 and downloads all you specify in lrp.conf. The packages are 
unpacked and the necessary links in the /etc/rc.x directories are 
recreated. Then the system is forced to init level 3 where all packages 
that require initialisation are started. The difference being is that your 
firewall now runs at init level 3 rather than 2.

Comments welcome
Have fun

Erich
