FYI, the default actually comes from src:kexec-tools:

cat debian/kexec-tools.grub
GRUB_CMDLINE_LINUX_DEFAULT="$GRUB_CMDLINE_LINUX_DEFAULT crashkernel=384M-:128M"

which, in and of itself, seems odd as if you only install kexec-tools,
you've now reserved some system memory for kdump.

And if you remove/purge kexec-tools, crashkernel= seems to stick around
:)
