Comment 6 for bug 1398478

Adam: This is because both e.g. serial-modules and squashfs-modules are pulled in by germinate from linux-udebs-generic, which depends on the latest versions in -proposed; but serial-modules is also pulled in from debian-installer-udebs, which depends on serial-modules-3.13.0-40-generic-di since debian-installer was last built against 3.13.0-40.

Unfortunately, the use of linux-udebs-generic, while convenient for other reasons, means that we can't use the usual Kernel-Version trick in seeds to limit to only the relevant kernel version, because linux-udebs-generic is an unversioned package name and so only the latest one is available in Packages. Using this unversioned package name means that debian-installer *must* be kept up to date, I think.
