Currently there's no way to distinguish between the two cases: - runc exec failed; - the command executed returned 1. This was possible before commit 8477638, as runc exec exited with the code of 255 if exec itself has failed. The code of 255 is the same convention as used by e.g. ssh. Re-introduce the feature, document it, and add some tests so it won't be broken again. Signed-off-by: Kir Kolyshkin <[email protected]>
