Activating distro layer in Yocto - yocto

Question

What are the required steps to use a distro layer in Yocto?
Currently, I have the following setup:
meta-my-distro-layer/conf/distro/mydistro.conf:
DISTROOVERRIDES =. "poky:"
require conf/distro/poky.conf
DISTRO = "mydistro"
DISTRO_NAME = "MyDistro"
DISTRO_VERSION = "1.0"
DISTRO_CODENAME = "one"
INIT_MANAGER = "systemd"
meta-my-distro-layer/conf/layer.conf
# We have a conf and classes directory, add to BBPATH
BBPATH .= ":${LAYERDIR}"
# We have recipes-* directories, add to BBFILES
BBFILES += "${LAYERDIR}/recipes-*/*/*.bb \
${LAYERDIR}/recipes-*/*/*.bbappend"
BBFILE_COLLECTIONS += "meta-my-distro-layer"
BBFILE_PATTERN_meta-my-distro-layer = "^${LAYERDIR}/"
BBFILE_PRIORITY_meta-my-distro-layer = "6"
LAYERDEPENDS_meta-my-distro-layer = "core"
LAYERSERIES_COMPAT_meta-my-distro-layer = "kirkstone"
meta-my-distro-layer/recipes-core/images/console-image.bb
DESCRIPTION = "A console-only image"
IMAGE_FEATURES += "ssh-server-openssh"
IMAGE_INSTALL = "\
packagegroup-core-boot \
packagegroup-core-full-cmdline \
${CORE_IMAGE_EXTRA_INSTALL} \
"
inherit core-image
IMAGE_INSTALL += "curl"
build/conf/bblayers.conf:
# POKY_BBLAYERS_CONF_VERSION is increased each time build/conf/bblayers.conf
# changes incompatibly
POKY_BBLAYERS_CONF_VERSION = "2"
BBPATH = "${TOPDIR}"
BBFILES ?= ""
BBLAYERS ?= " \
/my-work-dir/poky/meta \
/my-work-dir/poky/meta-poky \
/my-work-dir/poky/meta-yocto-bsp \
/my-work-dir/poky/meta-my-distro-layer \
"
I can build the console image defined in that layer, but nothing set in mydistro.conf seems to have any effect on bitbake. According to bitbake -e, DISTRO and INIT_MANAGER never get set to my values and (consequently) trying to set INIT_MANAGER to systemd never takes effect. I can set INIT_MANAGER in conf/local.conf and it takes effect then, but I'd like to do that in a distro layer.

You need to set DISTRO to mydistro in local.conf
