When accepting luser console login, pam_console called by /bin/login tries to be user-friendly, doing several chowns on devices like login tty and corresponding vcs[a] device, as well as other interesting devices: fd*, audio devices (dsp*, mixer*, audio*, midi*, sequencer), cdrom, streamer/zip drive devices, frame buffer devices, kbd*, js*, video*, radio*, winradio*, vtx*, vbi* and so on. Probably it's designed to make console logins more comfortable, but has DEADLY effects on servers with console luser-login ability (and that's quite common).
