Comment 12 for bug 1611945

@zbyszek-in: would you be willing to take patches that upstream refuse? There's a fix for this via https://github.com/sitsofe/systemd/commit/ee26c33ede684138ba9fdc7f286bfa402860aff3 but upstream have a clear "no more changes will ever be made to systemd provided storage udev rules" rule : https://github.com/systemd/systemd/issues/3943#issuecomment-240982482 . I can attach the patch here if required...
