[Bug 1870810] [NEW] Grub update fails on zfs root drives after software install..

[Jeff Hoffman]

Public bug reported:

My grub.cfg file first menu entry works.  Used to refer to specific hard
drives which will not work with ZFS root devices.

It also loops and adds another "}" at line 183.

Memtest again refers to /dev/sd<x> which I don't think will work with
ZFS filesystems?

See the two files attached.

grub.cfg I modified to make it work to see first menu entry or linux*88
menu entry.

The second one is the generated grub.cfg.new which is bad.
