Feedback from upstream at https://github.com/systemd/systemd/pull/1265 : Apparently noexec on /dev breaks some drivers which expose memory-mapped devices in /dev/. So retitling for "nosuid" only. systemd already does that, initramfs-tools doesn't yet, but the attached patch needs to be modified to only set "nosuid".

I committed http:// anonscm. debian. org/cgit/ pkg-systemd/ systemd. git/commit/ ?id=470c174f so that under sysvinit and without initramfs-tools udev will now mount /dev with "nosuid" as well. This case doesn't apply to Ubuntu, so once again closing the systemd task.
