In case of a typo in the MENU_ENTRY parameter both grub-set-default and grub-reboot utilities exit with no error message and with successful exit status. After the reboot grub will try to load the first menu entry found in grub.cfg

I believe it it a very serious issue. In case if the first entry refers to an unbootable configuration on a remote server, it leads to total loose of the system until physical access is possible!

Steps to reproduce:

# grub-set-default blahblahblah && echo success

Expected results:

1) A error message
2) No change of the default menu entry upon reboot

Actual results:

1) Message 'success' is printed
2) The default menu entry in changed to the fist entry in grub.cfg upon reboot

The same issue on my distribution's tracker:
