[OpenIndiana-discuss] Fastboot not working on Hipster-2015.03.30

[Oscar del Rio]

Fresh install of Hipster-2015.03.30 plus pkg-update (illumos-bde3d61) on a 
Dell PowerEdge R220.

Everything seems to be working great, except "fastboot".
When rebooting, the following error is shown:

reboot: Failed to process GRUB menu entry for fast reboot.
         Invalid format for findroot
reboot: Falling back to regular reboot.

Not a big deal, just slow reboots, but just thought to mention it in case it 
is a new bug.

rpool is on mirror-drives, full disks:
         rpool       ONLINE       0     0     0
           mirror-0  ONLINE       0     0     0
             c2t0d0  ONLINE       0     0     0
             c2t1d0  ONLINE       0     0     0
