AW: Handle errors when booting

[Mathias Radtke]

Hi


Upstream efi/chainloader.c does not have 733 lines nor does it care
about $root at all. You are probably using vendor patched grub, in
which case you better direct this question to your vendor support
channels.

The code source is 

http://deb.debian.org/debian/pool/main/g/grub2/grub2_2.06.orig.tar.xz
We apply various patches to this codebase and build it outselves.

What is the exit code of chainloader command? If it is non-zero, you
can check for it and do something else instead of boot.





Could you provide an example of such a check?
Like if in my example the chainloader returns anything that is not zero, then 
exit from grub. 


Thanks in advance
