Hi.
I'm trying to boot several live ISO's using my PXE-boot server and Grub
loopback. ISO's are fetched by Grub from an HTTP server on the same host.
* I can boot the kernels of all live ISO's through PXE+HTTP transfer.
* Boot process fails at mount-root stage, where rootfs will obviously be
Hi Andrei, thanks for the answer.
You need to tell your kernel/initrd where to find ISO and it should be
able to fetch data from it via HTTP.
I was advised on debian-live, if ISO contains httpfs, you can boot by pointing
the live initramfs to the iso location on your web server; essentially
I have two separate issues involving the {kfreebsd} code in grub.cfg:
* First is, code snippet to get mount_root to use NFS V3 instead of V2. The
code for this in FreeBSD's /boot/loader.conf is: {boot-nfsroot-options=“nfsv3”}
The comparable grub.cfg code should be as below, but does not work
* First is, code snippet to get mount_root to use NFS V3 instead of
V2. grub.cfg code should be as below, but does not work
This should be kFreeBSD

Is there a method to chainload from grub2 - grub_older
and grub2 - isolinux?
Most live-cd's use an isolinux configuration with many menu items
embedded in the isolinux layer.
Instead of spending time trying to guess at these, a chainload boot
would be most helpful.
Thanks and Regards.

GRUB has isolinux config parser.
Is there any link to usage with examples? The Grub manual does not
mention it all I could find was from osdetect.cfg:
syslinux_configfile -i /isolinux/isolinux.cfg
Which still isn't much to go on.
