Switching for udev to eudev, leaves dead symlink for udev-save init script. Can be found in /etc/runlevels/shutdown udev-save --> /etc/init.d/udev-save is broken symlink Reproducible: Always
Please post your `emerge --info sys-fs/eudev' output in a comment.
I don't see any evidence of anything installing that symlink. We really need more information here.
