[Nexus 9 Q&A, Help & Troubleshooting] kc27:
Below is what I saw on screen when I did a clean install of Android 6 to my Nexus 9 32gb tablet. I've included the entire terminal screen text below. Immediately below is the part I am wondering about. It says archive does not contain boot.sig, recover.sig, etc, and also file system type f2fs not supported, but then if you look in the full output below, after it reports that the archive does not contain those items, it proceeds to send them to the tablet.

archive does not contain 'boot.sig'

archive does not contain 'recovery.sig'

archive does not contain 'system.sig'

archive does not contain 'vendor.sig'

Erase successful, but not automatically formatting.

File system type f2fs not supported.

I did the install about 12 hours ago, and the tablet has run fine since then, so I believe that the install is OK. But can someone who is more familiar with doing installs take a look and tell me if they see anything amiss, or has advice on what actions, if any, I need to take.

Thanks in advance for your help.
