config init?

Many thanks, Colin. And a Happy New Year!

May I ask you if what I am hoping to do makes sense? Taking the gist =
from =
http://www.daemonology.net/blog/2015-11-21-FreeBSD-AMI-builder-AMI.html =
I plan to make an AMI, install packages, patch and install the kernel, =
all in one go. I am unsure how to =E2=80=9Cmake kernel=E2=80=9D so that =
it ends up in the new AMI, rather than just in the builder AMI.

Firs, I create an IAM role with a policy which grants access to the EC2 =
CreateImage API. Then I launch your AMI building AMI ami-e6a6ea9c in =
us-east-1 using config init script as follows, on a sufficiently large =
c5:

#!/bin/sh
export ASSUME_ALWAYS_YES=3DYES
PKGS_TO_INSTALL=3Dlots of packages go here
pkg -r /mnt fetch -d $PKGS_TO_INSTALL
pkg -c /mnt install $PKGS_TO_INSTALL
svnlite co https://svn.freebsd.org/base/releng/11.1/ /usr/src/
cd /usr/src
cat > /tmp/kernel.patch <<EOT
Patch goes here
EOT
patch < /tmp/kernel.patch
make kernel -j16
*** How to copy the new kernel into the AMI=E2=80=99s kernel on /mnt =
without messing anything up ***
mkami "FreeBSD 11.1 for PB=E2=80=9D =E2=80=9CPB Customised FreeBSD"
shutdown -p now

Afterwards I copy my new AMI to eu-west-1.

Does this make sense? Is there documentation to mkami? I could not find =
it. I am curious if I could parametrise it to create an encrypted volume =
snapshot of a given target size.

Many, many thanks and my regards from Ireland,
Rafal=
