About multi-boot with OpenBSD, OpenIndiana and GNU/Linux. Grub don't detect OpenBSD and OpenIndiana.

[nureo]

   Well. Hello to everybody.

   I asked about my problem in the Trisquel GNU/Linux forum 
[https://trisquel.info/en/forum/arranque-dual-con-openbsd-y-trisquel-grub-no-reconoce-openbsd]. 
But, for what I'd see in other places, the problem can be in GRUB it 
self.

   I installed OpenBSD, OpenIndiana, and Trisquel GNU/Linux. The 
Trisquel GRUB (2) doesn't recognize the others systems. I did try with 
"sudo update-grub". And it doesn't seams to recognize the others 
systems.

   I give you this 2 pictures, with my partitions. GRUB is in 
"/dev/sda".

   What can I do? Is there a solution for this?

   Thanks for your time.
