Details:
Hello,
in Ubuntu we are working on making it easier to capture kernel
crashes. The system we use is based around kdump and it works by
triggering a kexec of a special crashdump kernel if the regular
kernels crashes. In order for this to work the normal kernel needs a
additional commandline option "crashkernel=".
Attached is a very simple patch that adds this option automatically if
kexec and makedumpfile are available.
If its not general enough for inclusion into the default grub2, may a
mechanism to pass additional kernel commandline paramters via some
sort of defaults.d/ directory would be the right apporoach? Then I
could just ship a config file in kexec-tools that looks like this:
GRUB_LINUX_CMDLINE_EXTRA="$GRUB_LINUX_CMDLINE_EXTRA
crashkernel=384M-2G:64M,2G-
:128M"
Thanks,
Michael
