Actually I was wrong, on some boxes with coreutils_8.21-1ubuntu5.4 it was working fine. This is really an initramfs-tools bug: https://bugs.launchpad.net/ubuntu/trusty/+source/coreutils/+bug/1535349
I had the version with the fix, but needed to reboot again to get it to take effect I guess. Rebooting after initramfs-tools - 0.103ubuntu4.3 fixed the issue everywhere for me even on coreutils_8.21-1ubuntu5.4
