The updated initscripts should be uploaded to experimental later today.
This includes all the changes listed above.

I've added the block above because we can't make an upload of sysvinit/
initscripts to unstable until we have an updated initramfs-tools in
unstable, or else udev will break.  Therefore in order to have a smooth
transition we need initramfs-tools uploading first, followed by

Marco, have you tested this upgrade path?  That is /run in the
initramfs and no /run on the rootfs?  Is udev checking for that and
not using /run in this scenario (or moving the files from /run to
/dev/.udev)?  We will need to cope with this for a brief transitional
period when initramfs-tools is updated and initscripts is not.
