I modified 10_linux_zfs to comment out the set -e and add the variables
for pkgdatadir and the GRUB* variables from /etc/default/grub and ran it
to see the output.
Notice at the end the double brace, lack of initrd value and linux image
even though it was found at the beginning when it correctly identified
the root dataset.
jpb@explorer:~/test$ sudo ./10_linux_zfs
