Is there a good way to maintain a small number of local customizations/patches
while staying synced with upstream changes? So far all my attempts have run
into various gotchas. This is what I currently believe:
Using a different recipe name breaks implicit directory names and specialized
variables. (example: using a modified machine file)
Using a different recipe name with PROVIDES and PREFERRED_PROVIDER still causes
the original package to be built, with possible conflicts. The only way around
this would seem to be patching every single reference in OE to use a virtual
target. (example: using directfb with a graphics driver; other packages still
depend on just 'directfb')
Patches and other files are relative to the top level recipe, so it is
necessary to copy all patches etc when using an overlay. This also applies
when using 'inherit.' Linking can get around this a little bit, but only if
you don't need to include a custom patch, inside one of the file trees.
(example: making small changes to a kernel defconfig, while the kernel is under
active development)
