[Grml] Help booting using iPXE

[Alex Rozenshteyn]

I recently ran into netboot.xyz and, being sad that it didn't support my
favorite live distribution filed a feature request
<https://github.com/antonym/netboot.xyz/issues/70>. I got an old image I
had lying around to boot (specifically, grml64-small_2013.09.iso), but I
couldn't get grml64-small_2014.11.iso to boot.

When I try (testing in VirtualBox), the startup complains "modprobe: module
dm-raid45 not found in modules.dep" and about module "echi-orion" and gets
stuck at an initramfs prompt with the message "Unable to find a medium
containing a live file system".

Booting the same iso directly works correctly. Any advice?

I tested using netboot.xyz on the grml64-small_testing_build1520.iso (with
sha1 9d7135a1a8b4fd22948245f3384137abb521fa8f) and experienced the same
failure condition; booting the iso directly succeeded (again, both in
VirtualBox).

Oh nice, thanks :)

Those are just cosmetic issue and can be ignored.

Ah hm, looking at
https://github.com/antonym/netboot.xyz/commit/1a00e17fd07577aed57a9c560ab513346b5ff808
I'd say that memdisk support in live-boot (which is used in Grml
boot process and responsible for memdisk support) might be broken
then?
Could you maybe test it with a more recent Grml version (our daily
builds) from http://grml.org/daily/ ?

apt-get install grub-imageboot
mkdir /boot/images
cd /boot/images
wget http://download.grml.org/grml64-small_2014.11.iso
update-grub
reboot
and this hangs in an endless loop as well. Adding debug=1 boot
option shows that it's failing to detect the filesystem, so
something indeed seems to be fishy with recent versions of
live-boot. :(
I've reported this as http://bts.grml.org/grml/issue2165 in our BTS.
thanks && regards,
