Can you please try adding the following code after line 36 to /etc/grub.d/42_grml:
$(prepare_grub_to_access_device ${GRUB_DEVICE_BOOT}) | sed -e "s/^/ /")
so /etc/grub.d/42_grml looks like:
[...] cat << EOF menuentry "${title}" { $(prepare_grub_to_access_device ${GRUB_DEVICE_BOOT} | sed -e "s/^/ /") iso_path="${rel_dirname}/$grml $CUSTOM_BOOTOPTIONS" [...]
If that works for you I'd apply this fix and upload a new version of grml-rescueboot.
Your line had a typo (the first ")" has to be removed), then I can get the Grml menu (I've joined my 42_grml file for reference).
Wupps, right.
You can add debug=vc manually to the kernel cmdline in Grml's bootsplash or just select the debug menu entry if you want a more verbose boot mode.
Notice that you don't need the forensic mode for this situation as Grml won't use your swap partition unless you explictely request to do so.
Thanks for the precision.
I still have a problem booting Grml, but I don't see exaclty what is wrong and how it can work for you ;-) my Grml booting problem is that live system doesn't find the ISO, because of problem in kernel command line : I get a kernel command line (from my memory) like : apm=power-off quiet ... iso="/boot/grml/grml64-medium_2010.12.iso " ...
The problem comes from the quotes around ISO path, as set in 42_grml : iso_path="/boot/grml/grml64-medium_2010.12.iso " (I don't at first set CUSTOM_BOOTOPTIONS, I then tried with some options, with the same result)
I have to remove quotes in iso_path definition to be able to boot, then in that case, I lose optional boot options set in CUSTOM_BOOTOPTIONS).
I've tried to understand how Grml's Grub menu works (with variables like "${isoopts}" "${kernelopts}", i'm not sure about the first variable name), but I don't understand where these variables are set, and how to have a correct boot command with optional BOOTOPTIONS.
Thanks to your excellent hints I could spot the problem. I just uploaded grml-rescueboot 0.3.0 to grml-testing that should fix this issue.
Sadly there's still a problem with CUSTOM_BOOTOPTIONS when having more than one option (so CUSTOM_BOOTOPTIONS="ssh=password" works but CUSTOM_BOOTOPTIONS="ssh password lang=de" fails). I've an idea how this could be resolved but this needs further testing.
Anyway, your main issue should be fixed - please let us know whether it works for you!
