Subject: netfilter-persistent.service shouldn't require systemd-modules-load.service

Date: Wed, 12 Nov 2014 16:28:47 -0700

Package: netfilter-persistent
Source: iptables-persistent
Version: 1.0.2
Severity: important
Tags: jessie

I'm running Debian Jessie on Linode's kernel on multiple VM. It works
great. However, I started having this error recently:

Linode doesn't provide /lib/modules/kernel-linode/modules.builtin, but
this shouldn't be a problem.

Thank you.

I guess this could be fixed in systemd as well.

The fixes are either systemd-modules-load.service shouldn't require 
modules.builtin, or netfilter-persistent.service shouldn't depend 
systemd-modules-load.service.

I suspect, the real problem is the failure to load the loop module.
Which either looks like a bug in your configuration or the kernel
missing that module.

Why should that not be a problem if modules.builtin is missing?

https://www.kernel.org/doc/Documentation/kbuild/kbuild.txt says, that
you really want that, if you don't want modprobe to not fail for builtin
modules.

Is loop builtin in your case?

In the case of Linode, they boot on a third party kernel which doesn't 
provide anything in /lib/modules/ because the kernel is not on the disk.

Another use case would be if you were to boot on a PXE kernel which has 
every of its modules built-in. You want to fail silently if 
/lib/modules/kernel/modules.builtin doesn't exist.

Yes. Loop is builtin.

Do you have loop in /etc/modules or /etc/modules-load.d/*?

If so, the error is expected behaviour, as outlined above.
If you don't want the error, either ship a modules.builtin with your 
kernel or don't try to load a builtin module.

Okay. Nevermind, you're totally right. 'loop' is in /etc/modules.
This is a bug between the chair and the keyboard.

Sorry about that.

Thank you.

Appending a -done to the bug number in the email adress closes the bug 
[0]. See [1] and [2] how to manipulate bug reports.
