Adding ISO boot to lilo

[ruymbeke]

Thank you very much Gilles, it is now working thanks to your miniroot. The same machine also had a "traditional" PMI (KNOPPIX cloop copy, not directly from ISO), which I had to rename, though. Is there a way to avoid the scanning for KNOPPIX/KNOPPIX iimages under all detected filesystems which seems to take precedence over the "bootfrom" method?

Yes technically it is possible, but I always try to minimize the changes from the official linuxrc
in order to reduce the risks and simplify the upgrade from releases to releases.
This is one of the quite complicated and somewhat not that well written part of the linuxrc boot script.
Since it is not very desirable to modify the iso file to make it work,
I suggest to rename your KNOPPIX/KNOPPIX cloop file path (as you have done) and update
accordingly your kernel bootloader command line with the knoppix_dir and/or knoppix_name cheatcodes.

Also, I am curious, does the stock knoppix never work off NTFS, but only through your corrected minirt? That'd be a worthwhile addition to the standard release, it seems!

So far yes and I would like to see it in the next release as well, but this is really up to Klaus.
I tried several times to propose my solution via the debian-knoppix mailing list but without success.
Nevertheless I may understand one reason for Klaus not having done it yet:
For some mysterious reasons to me, Isolinux (which is used by Knoppix to boot the cd/dvd)
doesn't look like capable to handle large minirt boot ramdisks. Reason for Knoppix to now have
a \boot\modules directrory on the cd to store the modules that cannot fit inside the minirt.
The minirt file had to grow in order to contain the ntfs driver and some other tools
for the double loopback required for the iso boot. And obviously the ntfs driver cannot be read
from the /boot/modules directory since it will require the ntfs driver to perform the ntfs read from the iso.
A complete remodeling of the linuxrc and the minirt could make sense but there is an other work around.
I couldn't remaster Knoppix with my minirt when using isolinux but it works great
when I use grub as the cd/dvd bootloader (bootloader also used by the Kanotix cd), cf:
http://www.knoppix.net/forum/viewtop...?p=99669#99669
I wish that Klaus will consider a grub boodloader for his cd/dvd and then use an improved minirt
with ntfs support and some of my other addons as custom static and dynamic hostnames (mac_adr or time), ...
Best Regards,
Gilles
