I should add that I was able to use this technique to fix a bug that I |
| 8 |
encountered during my initial attempt to port Illumos GRUB a month |
| 9 |
ago. The code the introduced the Illumos GRUB bug is not present in |
| 10 |
sys-boot/grub, but I imagine that the same technique should work here. |

Also, for anyone interested in what happened to the |
| 13 |
sys-boot/grub-illumos port I mention, there are issues with the |
| 14 |
generated stage2 binary, grub-install is broken (Solaris uses a |
| 15 |
separate install-grub tool) and I would prefer to rework the Sun |
| 16 |
Microsystems code into a patch for sys-boot/grub, but the diff between |
| 17 |
Illumos GRUB and GRUB 0.97 is a few megabytes in size, so that won't |
| 18 |
happen this month. |
