Hello Michael,

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).
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.
Perhaps you'll have some ideas about this,
with regards,
Fred.
