Package: grub
Version: 0.97-41
Severity: grave
Hello,
thanks for maintaining grub.
Running update-grub segfaults:
# update-grub ; echo $?
Searching for GRUB installation directory ... found: /boot/grub
139
(139 = 128 + 11, 11 = SIGSEGV)
This is a trace of the script:
# sh -x `which update-grub`
+ set -e
++ uname -s
++ tr '[A-Z]' '[a-z]'
+ host_os=linux
++ find_grub_dir
++ echo -n 'Searching for GRUB installation directory ... '
Searching for GRUB installation directory ... ++ for d in /boot/grub
/boot/boot/grub
++ '[' -d /boot/grub ']'
++ grub_dir=/boot/grub
++ break
++ '[' -z /boot/grub ']'
++ echo 'found: /boot/grub'
found: /boot/grub
++ echo /boot/grub
+ grub_dir=/boot/grub
+ device_map=/boot/grub/device.map
+ menu_file_basename=menu.lst
+ menu_file=/boot/grub/menu.lst
+ default_file_basename=default
+ default_file=/boot/grub/default
++ find_device /
++ test -e /boot/grub/device.map
++ grub-probe --device-map=/boot/grub/device.map -t device /
+ root_device=
And this is the core of the problem:
# grub-probe --device-map=/boot/grub/device.map -t device /
Segmentation fault
This is the /etc/fstab line related to '/':
/dev/sda1 / ext3 defaults,errors=remount-ro,relatime 0

Cheers,
