Bug Description

Binary package hint: grub

I have my /boot partition mounted read-only. Trying to use grub-reboot in this situation results in the program segfaulting.

$ sudo grub-reboot 1

grub> savedefault --once --default=1
/usr/sbin/grub-reboot: line 68: 6599 Segmentation fault (core dumped) grub --batch --config-file=$config_file $@ <<EOT

The command worked fine after I remounted /boot read-write.
