CloneZilla USB, unattended syslinux, need translation to grub-equivalent - linux

Question

I have a bootable CloneZilla on USB. It works great with systems that boot using syslinux. Here's the menu entry in syslinux.cfg and a short description of what it does (note that I use & to imply that it's the same line, I broke it up to multiple lines for readability):
label Clone Default Image
#MENU DEFAULT
MENU LABEL Clone from \\bilbo
kernel /live/vmlinuz
append initrd=/live/initrd.img boot=live union=overlay config quiet noswap
& noeject nosplash username=user hostname=yakkety components edd=on nomodeset
& noprompt nolocales keyboard-layouts=sv locales=sv_SE.UTF-8
& ocs_live_run="ocs-sr --batch -g auto -e1 auto -e2 -r -j2
& -p poweroff restoredisk windows-10-base-clone sda" ocs_live_extra_param=""
& ocs_live_batch=no vga=791 ip= nosplash i915.blacklist=yes radeonhd.blacklist=yes
& nouveau.blacklist=yes vmwgfx.blacklist=yes
& ocs_repository="smb://administrator:**********#192.168.10.41/common/utveckling/clone"
& {lots of ocs_preruns to setup dhcp on one of two possible eth-interfaces}
It setups an eth-interface to use dhcp. It then tries to mount a samba share, as seen in ocs_repository="user:pass#path". After that, it should run the ocs_live_run="cmd" entry, which performs a clone from the samba location to the main disk of the booted device.
This is my attempt at creating an equivalent grub.cfg entry:
menuentry "Clone from \\\\bilbo"{
search --set -f /live/vmlinuz
linux /live/vmlinuz boot=live union=overlay config quiet noswap
& noeject nosplash username=user hostname=yakkety components edd=on nomodeset
& noprompt nolocales keyboard-layouts=sv locales=sv_SE.UTF-8
& ocs_live_run="ocs-sr --batch -g auto -e1 auto -e2 -r -j2
& -p poweroff restoredisk windows-10-base-clone sda" ocs_live_extra_param=""
& ocs_live_batch=no vga=791 ip= nosplash i915.blacklist=yes radeonhd.blacklist=yes
& nouveau.blacklist=yes vmwgfx.blacklist=yes
& ocs_repository="smb://administrator:**********#192.168.10.41/common/utveckling/clone"
& {same preruns, it seems to work well}
initrd /live/initrd.img
}
For whatever reasons, the grub one fails. It seems to try to do the same things, but I would wager that there's something going wrong with mounting the samba-location (I can mount it manually).
It stops with the error message "/home/partimag/windows-10-base-clone" does not exist, which certainly should exist, had it mounted the provided samba location to /home/partimag/.
Any suggestions?

Answer 1

I was having a very similar issue, and I noticed by adding longer 'sleep' calls that the mount command invokes the help file for mount, so I knew that there was a syntax error, but the same syntax works in the iso/syslinux.cfg and at prompt after the ocs_live_run fails.
I discovered that the ocs_prerun="Mount..." won't run without escaping the " with \.
Thus:
OCS_PRERUN5=\"Mount -o user=,pass= //host/path/ /home/partimag\"
I hope that if you are still working on this it works for you also.
