Hi!
There is a rather annoying usability problem with grub-reboot. When the bootdir is on a device with disabled environment block writes (https://www.gnu.org/software/grub/manual/html_node/Environment-block.html - lvm, raid, zfs ...), next_entry is never cleared.
This means that the boot option set with grub-reboot is not used only once but always - even after running update-grub the boot option selected to boot once is still used by grub(!) - the user must debug the problem all the way down and, for example, delete /boot/grub/grubenv.
Patch attached prevents grub-reboot working on a device with lvm or raid or zfs or btrfs.
Thanks!
Lucas
