Grubs really aren't very attractive...

os-prober much better?

I disagree!  with old grub, FreeBSD was detected.  Now it was a major pain to get to triple boot a machine.  I had a typo and thanks to folks here on test list, I got it going.  But I had to play around with 40_ custom and add the freebsd entry there and then modify /etc/grub2/custom or whatever it is called so I could remove the rhgb and quiet parameters and then run 
grub2-???. Initially I had edited it manually and removed the lines.  But then kernel updates made the rhgb quiet come back :(

You have to fool grub2 and modify _10 add a number less than that so it could become the default, but it is workable.

I read and read and read again many times.  The documentation is not up to par.  However being perseverant and asking help about a situation and caring people willing to help, then these issues are not major.  But it is far from being easy.

The question here for Tom or others, that used to install grub to a specific partition and use chainload to boot the different OSes, is indeed a pain with this grub2.  But with extra help, and patience, It can be done.  Tom has worked it out, but I wonder if he has saved the changes in the /etc/grub2/default file so that updates won't mess any of his changes?
