In my environment I have a problem to halt the system, every time I halt th
systsem, the kernel issues a reboot. (for reference see:
To circumvent the problem I use the grubenv feature of grub issuing a:
"grub2-reboot 'halt'" and a "shutdown -h now"
obviously there is an entry in the grub2 config file that is:

menuentry 'halt' --class opensuse --class halt {
  echo "halting system"
  sleep 5
  set saved_entry=0
  save_env saved_entry

so when I firstly run shutdown -h now, the kernel issue a reboot but observing
the grub2-reboot 'halt' command, grub shutdown the system. Then I can power on
my system and grub "forget" to boot 'halt' and boots properly.

This work when the boot filesystem is on a real partition but, as I have
bought a new hard disk, and grub2 permit the full use of lvm2 (insmod lvm) I
configured my system also with the boot partition as lvm2 logical volume.
Normal boot works but, when I issue grub2-mkboot 'halt' the grub correctly use
it and halt the system but, when I power-up again it continues to boot 'halt'
so I'm in a dead lock. Probably there is a issue in grub2 that don't permit to
upgrade (from grub) the grubenv file....
