Yeah, Yann already said that on IRC when I asked him about this patch.
You guys are really in sync! :)

The thing is that Linux and U-Boot are not the regular package, since
almost every BR user using it for a custom product will need to
customize the kernel and the bootloader to some extent.

At least from my perspective, it's nice to have the patches (instead
of pointing to some git branch) and be forced to see what
modifications I'm using.

And to produce the patches, I use git-format-patch (aren't we all?),
which doesn't allow to specify a prefix for the patches. This has been
discussed and rejected, so don't think the feature will ever be added.

Sure, I can use a script, but these options seemed natural enough and
it allows for a simple "git-format-patch" run and dump the files to a

Anyway... this is just my use case. I understand your desire to remove
strange options and reduce the churn.
