I suggested that camcontrol is not the right place to get disk ident strings, since not all disks are CAM, and suggested an alternative. 2. I pointed out a possible bug related to MBR setup and suggested a solution. 3. I asked you to update the man page to reflect the new features, as well as update a few other scripts to allow them to use your ZFS code. 4. I requested a somewhat longer testing period and additional review for future significant installer changes like this in the run-up to a release and tried to explain my rationale. 5. I suggested that the "Submitted by" and "Reviewed by" should probably not be the same person. I also thanked you for the patch, which adds a sorely-missed feature to the installer. I do not believe that any of these minor requests were unreasonable. Certainly, I do not see that they merit the vitriol that follows here. Since it doesn't seem to help with anything, I won't send any more mail on this. The one thing I have done is to ask re@ to ensure that, following the usual conventions, all non-trivial patches to the installer proposed for merge to stable/10 be reviewed and have a reasonable testing period in HEAD or on mailing lists before being MFC'ed for the remainder of the 10.0 release process. -Nathan On Sun, 13 Oct 2013, Teske, Devin wrote: > > On Oct 13, 2013, at 12:41 AM, Nathan Whitehorn wrote: > >> >> >> On Sat, 12 Oct 2013, Teske, Devin wrote: >> >>> >>> On Oct 12, 2013, at 12:26 AM, Nathan Whitehorn wrote: >>> >>>> On 10/11/13 22:41, Devin Teske wrote: >>>>> Author: dteske >>>>> Date: Fri Oct 11 20:41:35 2013 >>>>> New Revision: 256343 >>>>> URL: https://urldefense.proofpoint.com/v1/url?u=http://svnweb.freebsd.org/changeset/base/256343&k=%2FbkpAUdJWZuiTILCq%2FFnQg%3D%3D%0A&r=Mrjs6vR4%2Faj2Ns9%2FssHJjg%3D%3D%0A&m=LDzuPpXPP4D5BzfISZjw%2BXitYn4aKVzfXzcrmMNFo2U%3D%0A&s=3d0963d9c497f7bad0918888032ca62844580612dc48ab3a8a6768fe640c365b >>>>> >>>>> Log: >>>>> Add zfsboot module as an option for automatic configuration.

In particular, you need to run gpart -F destroy recursively on the disk instead of just on the root node.
