The linux-image package currently includes empty hook directories (/etc/kernel/{pre,post}{inst,rm}.d/ by default). These directories were perhaps intended as a fail-safe in case no hook scripts exist there. However, they are really unnecessary because the run-parts command is already guarded by the following check: test -d ${debhookdir}/${script}.d && run-parts ... The only difference is that the run-parts command either runs for empty directories (resulting in a no-op) or is skipped entirely. The maintainer scripts will succeed without these dummy directories. The linux-image packages from the Debian kernel do not contain /etc/kernel/*.d/, either. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
