Comment 0 for bug 1430323

as reported by pitti under bug 450463, the cloud-images have the following in /etc/modules:
  | # LP: #450463
  | acpiphp

That is written by http://bazaar.launchpad.net/~ubuntu-on-ec2/vmbuilder/automated-ec2-builds/view/head:/vmbuilder-cloudimg-fixes

The result is that the systemd-modules-load.service fails to load, and user sees messages like this on console (possibly other fallout).

| [[32m OK [0m] Started Nameserver information manager.

Ideally there would be a way to say "load this if it exists", or some other way that failed module loads could be marked as non-fatal.
That said, as Martin reports, the acpiphp module is no longer present in vivid (3.19.0-7-generic).

For reference:
utopic:
 $ find /lib/modules -iname "*acpi*" -type f
/lib/modules/3.16.0-31-generic/kernel/drivers/acpi/acpi_ipmi.ko
/lib/modules/3.16.0-31-generic/kernel/drivers/acpi/acpi_pad.ko
/lib/modules/3.16.0-31-generic/kernel/drivers/acpi/acpi_extlog.ko

$ find /lib/modules -iname "*acpi*" -type f
/lib/modules/3.13.0-46-generic/kernel/drivers/acpi/acpi_pad.ko

/lib/modules/3.13.0-46-generic/kernel/drivers/acpi/acpi_extlog.ko

So we've been rid of acpiphp.ko since at least 14.04.
