Guillaume, you are a very imaginative guy. I will rename you
"Guillaume d'Orange". The idea of improve the
InstallationDisk (that's 1440k, and starts with loadlin) is a good one,
and I like to support you in this idea. But ftpget is not the only
requirement. You need of network commands (ifconfig, route), ethernet,
pppd, or I'm wrong?
Anyway, why you reversed the pipes in your example?
I thing you meant:
# ftpget -h host .... | gzip -d > /dev/ram15
# mount /dev/ram15 /usr

True; doesn't concern exactly, but can be intented as improvement of
the installation disk. It is only matter to add some new boot script,
a new derivation from the script /setup/rc/linuxrc
The easy way to do that is to add an entry in the section called
"MAIN switch", like:
===============================
elif [ "$ftp" ] ; then
mount /dev/fd0 /a
sh /a/init/ftpget.sh
exit 0
fi
===============================
Now if you add the keyword "ftp" on the boot command line, the system
mount the floppy and execute the script init/ftpget.sh.
In this script you can setup the network and download the images from
the ethernet.
With this solution, you can modify the file ftpget.sh (in the floppy)
without rebuild the root.gz image.
Why to not download the addons directly from the Sunsite.auc.dk server?
# ftpget .... XYZ.tgz > /dev/ram15
# setup -f XYZ from=/dev/ram15
In theory, you can download a complete root image and mount it as
/, using "losetup". Please, read this part in the linuxrc: this is how
the LOOP installation works. But this requires and hard-disk access.
