Наш проект имеет два слоя, каждый слой добавляет патч к одному и тому же файлу. Первый патч в слое с более низким приоритетом создает простой файл, слой с более высоким приоритетом, добавляет больше содержимого в файл. Эта операция всегда завершается неудачей в do_patch, потому что (несмотря на любой приоритет слоя), bitbake всегда сначала пробует второй патч, который завершается неудачей, поскольку файл еще не создан. Я показываю два журнала, в которых перевернут порядок .bbappend, но в обоих случаях второй патч ищется первым
