Everything has moved to /usr/bin, try init=/usr/bin/systemd
If you have removed the conflicting packages, then update filesystem,
msking the symlinks, so that /bin/* will not fail anymore.

Also, update more often and subscribe to arch-announce (or watch the
mainpage news), or consider moving to a non rolling-release distro, as Arch
tends to suffer from rare updates.
