[OE-core] [PATCH 5/5] devtool: update-recipe: add option to write changes to bbappend
Paul Eggleton
paul.eggleton at linux.intel.com
Mon May 18 15:15:08 UTC 2015
Quite often what you want to do having made customisations to a piece of
software is to apply those customisations in your own layer rather than
in the original recipe. Thus, add a -a/--append option to the
update-recipe subcommand which allows you to specify the layer to write
a bbappend into. The bbappend will be created at the appropriate path
within the specified layer directory (which may or may not be in your
bblayers.conf) or if one already exists it will be updated
appropriately.
(This re-uses code written for recipetool appendfile.)
Implements [YOCTO #7587].
