Hi.
I'm trying to boot several Debian based live ISO's (including Jessie) using my
PXE-boot server and Grub loopback method. ISO's are fetched by Grub from an
HTTP server on the same host.
* Using Grub's loopback, I can boot the kernels of all live ISO's through
PXE+HTTP transfer.
* Boot process fails at mount-root stage, which obviously will not be mounted
from NFS but rather from the ISO its self. Error message is usually similar
"could not find the ISO" or "unable to find medium containing a live file
system". On Debian_Jessie ISO, the install process starts, then complains that
there is no CD-ROM.
* Most PXE related solutions I come across involve extracting the iso image
before-hand, then calling the extracted vmlinuz and initrd. This is not of much
interest.
* A sample menu entry would be:
menuentry "Debian-testing-i386-lxde.iso"" --class gnu-linux --class gnu
--class os {
set root="http,192.168.2.100"
set isofile="debian-testing-i386-lxde-CD-1.iso"
loopback loop0 ($root)/iso/$isofile
linux (loop0)/install.386/vmlinuz
initrd (loop0)/install.386/initrd.gz
As stated, this boots the kernel but canot mount rootfs.
As the first step of solving this problem, what I'd first like to know is: When
booting an ISO over PXE+HTTP and mount-root fails, how can the rootfs on
live-CD be loaded to the ramdisk? Is ISO modification the only choice, or is it
possible to boot a normal ISO by passing the correct parameters to grub.cfg?
I'm not very interested in solutions that involve "generating custom debian
iso" or "downloading the Debian-PXE ISO". My main objective in asking the
question is to find a general solution for all Debian-based ISO's.
Regards
