dev-manual: Edits to "Creating a Custom Template Configuration Directory"
Fixes [YOCTO #5895] I applied some review comments from Paul to tighten up this section. (From yocto-docs rev: 9f17ad00e9e707fcd6f2419762b4281d64f4ed0f) Signed-off-by: Scott Rifenbark <scott.m.rifenbark@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

892 <title>Creating a Custom Template Configuration Directory</title>
893
894 <para>
895 You might find yourself repeating the same configurations for
896 a particular build or group of builds.
897 If so, rather than repeatedly editing your
898 <filename>local.conf</filename> and possibly your
899 <filename>bblayers.conf</filename>, you can set up a
900 custom directory that has your configurations, and then
901 point the OpenEmbedded build system to that directory to find
902 the configurations.
903 </para>
904
905 <para>
906 The OpenEmbedded build system uses the environment variable
907 <filename>TEMPLATECONF</filename> to point to the directory
908 from which it gathers configuration information that ultimately
909 ends up in the
910 <link linkend='build-directory'>Build Directory's</link>
911 <filename>conf</filename> directory.
912 By default, <filename>TEMPLATECONF</filename> points here:
913 <literallayout class='monospaced'>
914 TEMPLATECONF=${TEMPLATECONF:-meta-yocto/conf}
915 </literallayout>
916 This is the directory that the build system finds templates
917 with which to build some key configuration files.
918 If you look at this directory, you will see the
919 <filename>bblayers.conf.sample</filename>,
920 <filename>local.conf.sample</filename>, and
921 <filename>site.conf.sample</filename> configuration files.
922 The build system uses these files to form the respective
923 <filename>bblayers.conf</filename>,
924 <filename>local.conf</filename>, and the
925 <filename>site.conf</filename> configuration files it places in
926 the <filename>conf</filename> directory with the
927 Build Directory.
928 </para>
929
930 <para>
931 To override these default configuration files with
932 configurations you want used with every build, simply point the
933 <filename>TEMPLATECONF</filename> to your directory.
934 The <filename>TEMPLATECONF</filename> variable is set in the
935 <filename>.templateconf</filename> file, which is in the
936 top-level
937 <link linkend='source-directory'>Source Directory</link>
938 folder (e.g. <filename>poky</filename>).
939 Edit the <filename>.templateconf</filename> so that it points
940 to your directory.
941 Best practices dictate that you should keep your
942 template configuration directory in your custom distribution layer.
943 For example, suppose you have a layer named
944 <filename>meta-mylayer</filename> located in your home directory
945 and you want your template configuration directory named
946 <filename>myconf</filename>.
947 Changing the <filename>.templateconf</filename> as follows
948 causes the OpenEmbedded build system to look in your directory
949 and base its configuration files on the
950 <filename>*.sample</filename> configuration files it finds.
951 The final configuration files (i.e.
952 <filename>local.conf</filename> and
953 <filename>bblayers.conf</filename> ultimately still end up in
954 your Build Directory, but they are based on your
955 <filename>*.sample</filename> files.

962 Aside from the <filename>*.sample</filename> configuration files,
963 the <filename>conf-notes.txt</filename> also resides in the
964 default <filename>meta-yocto/conf</filename> directory.
965 The scripts that set up the build environment

967 <ulink url="&YOCTO_DOCS_REF_URL;#structure-core-script"><filename>&OE_INIT_FILE;</filename></ulink>
968 and
969 <ulink url="&YOCTO_DOCS_REF_URL;#structure-memres-core-script"><filename>oe-init-build-env-memres</filename></ulink>)
970 use this file to display BitBake targets as part of the script
971 output.
972 Customizing this <filename>conf-notes.txt</filename> file is a
973 good way to make sure your list of custom targets appears
974 as part of the script's output.
