I am not sure I like that because it means that if an user makes a
small mistake in the post-build script name/path, it will be silently
ignored by Buildroot. I'd prefer if Buildroot would fail loudly if it
is given a post-build script that doesn't exist/isn't executable, or
any other problem that prevents the script from being executed.
I'm not sure where you're getting ${BOARD_NAME} from, but why don't you
handle the board differences in the script itself?
Like:
BR2_ROOTFS_POST_BUILD_SCRIPT=board/<company>/<project>/post-build.sh
and post-build.sh:
====
#!/bin/sh
if test -e ${BOARD_NAME}-fixups.sh; then
sh ${BOARD_NAME}-fixups.sh
fi
====
No? :-)
