"This is already part of
v226"

Im trying to get rid of boot messages: Using lastest kmod
https://git.kernel.org/cgit/utils/kernel/kmod/kmod.git/commit/?id=114ec87c85c35a2bd3682f9f891e494127be6fb5

fixes this:
systemd[1]: Failed to insert module 'kdbus'

But using systemd 266 throws:
systemd[1]: Failed to insert module 'autofs4'

I have made 2 custom kernel for 2 Debian Stretch PC. Kernel 4.1.3 and 4.3 and I disabled autofs in kernel configuration, same happens in both systems. Setting LogLevel=crit in /etc/systemd/system.conf has no effect.

From the systemd code you can see that blacklisting autofs4 might help, but there is no sense to blacklist modules that do not exist in the kernel.
