[arch-general] no Boot after last kernel update

Hi, I could not boot after the last kernel update yesterday, I have no idea what happened, my screen stopped at the bootsplash, I could not even shutdown the machine from here. - Hard-Reset I had to use a live-CD to fix my system I have found that the syslinux.cfg was not automatically updated to see the new kernel. I moved /sda1/syslinux/syslinux.cfg to another place and mv /sda1/syslinux/syslinux.cfg.pacnew /sda1/syslinux/syslinux.cfg shouldn't this be done automatically? I don't remember this happening after the last kernel update...
