Package: kexec-tools
Version: 1:2.0.7-3
Severity: important
Dear Maintainer,
When USE_GRUB_CONFIG is true, and GRUB is set as
GRUB_DEFAULT=saved
GRUB_SAVEDEFAULT=true
the init script kexec-load tries to parse the selected kernel in GRUB menu and
calculate
the address from it. But the code doesn't seem to handle the case when the
saved kernel
is something like:
$ cat /boot/grub/grubenv
# GRUB Environment Block
saved_entry=gnulinux-simple-aecbc534-4764-4560-90c1-b02edc56ea23
################################################################
which is the case for stock Debian kernel.
in get_grub_kernel() function, [ "$default" = '${saved_entry}' ] evaluates to
true, so
default=$(sed -ne 's/^saved_entry=//p' /boot/grub/grubenv)
is run, and default is set to "gnulinux-simple-
aecbc534-4764-4560-90c1-b02edc56ea23"
when fed to "start_offset=$((default + 1))", it fails as:
/etc/init.d/kexec-load: 48: /etc/init.d/kexec-load: Illegal number: gnulinux-
simple-aecbc534-4764-4560-90c1-b02edc56ea23
I'm not sure if it's the right string but the parsing code is wrong, or the
string is
totaly wrong.
I'm attaching the grub.cfg.
