well, I hate to tell you, but 99% of the patch deals with stuff |
| 2 |
not related to the kernel reading cdroot off the command |
| 3 |
line. Also, CDBOOT was being put to the end of the rc.conf already, |
| 4 |
but it did not appear to work, and we are using the cdroot command |
| 5 |
line already specific to genkernel's initrd, so it was a non-wasteful |
| 6 |
way to implement it. |

I don't have time to argue on this stuff. The patch is sane, |
| 9 |
it needs to be committed, yes there are other ways to do it, |
| 10 |
but unless you have another option real soon, |
| 11 |
that is tested and works, we're going to need something |
| 12 |
in baselayout. |

Azarah, did you not get my patches? Have you looked at them? |
