Hi,
Aaron is right about his amazement.
info grub
...
 -- Command: default num
     Set the default entry to the entry number NUM. Numbering starts
     from 0, and the entry number 0 is the default if the command is not
     used.
...
So, the presence of default command is not required.

$ less /var/log/pm-suspend.log
...
/usr/lib/pm-utils/sleep.d/01grub hibernate hibernate: success.
...
$ less /usr/lib/pm-utils/sleep.d/01grub
...
out=$(/sbin/grubby --info /boot/vmlinuz-$(uname -r) |grep index)
...
echo "savedefault --default=${current} --once" | \
...

In this case, the default entry is the entry saved with the command
`savedefault'.

GRUB will choose the entry booted previously as the default entry.

Yes, Aaron. Do not let them off the hook :-)
