Let me resucitate this thread ...

I just tried this on Centos7 and expeience the same lack of grub menu.
I was able to work around it by manually entering the manual paths for
linux and initrd but wouldn't it be nice ...

However, on the Centos7 install, there appears to be both a grub/ and
grub2/ configuration directory:

  |
  | grub> ls (hd0,msdos1)/
  | Possible files are:
  |  grub/ grub2/ ...
  |

and in the grub2 folder there exists a seemling grub2 compatible grub.cfg file:

  | grub> cat (hd0,msdos1)/grub2/grub.cfg
  | #
  | # DO NOT EDIT THIS FILE
  | #
  | # It is automatically generated by grub2-mkconfig using templates
  | # from /etc/grub.d and settings from /etc/default/grub
  | #
  | 
<snip>

Is there a way to direct grub-bhyve to use the
centos:/boot/grub2/grub.cfg file ala some argument -- I scanned the
source and couldn't find a simple over-ride.

I'll test/rebuild the suite if you can point me in the general
direction.

Thanks,

dan
