grub2-systemd-sleep.sh

Thanks a lot for your information. It became clear that the blkid return code
aborted the execution prematurely but not skipping the offending entry and
continue to process the rest of config file as what we would expect.

Would you please help to verify the attached script grub2-systemd-sleep.sh ?
You could start by backup original grub2.sleep file

  cp /usr/lib/systemd/system-sleep/grub2.sleep grub2.sleep.bak

And copy the test script for the hibernation
  cp grub2-systemd-sleep.sh /usr/lib/systemd/system-sleep/grub2.sleep

Thanks.
