This reminds me of bug 1351295. For the main "init" initramfs script and local partitions there is code to get along with absolute symlinks. I don't see any readlink in the nfs script, but I figure this is a related problem. I see the Debian package has a fix for this: http://anonscm.debian.org/cgit/kernel/initramfs- tools.git/commit/scripts/nfs?id=7bc24f829f
Would you mind testing this? I. e. please put the attached "nfs" script into /usr/share/initramfs-tools/scripts/, revert /sbin/init to be an absolute link to /lib/systemd/systemd again, run "sudo update-initramfs -u", and check if booting now works?

Making that link a relative path fixes the problem (i.e. making it ../lib/systemd/systemd). Please, see /usr/share/initramfs-tools/scripts/nfs for the affected script. I believe this should be fixed before the release of 15.04, as it breaks all nfs root installs.
