Created attachment 87171

workaround PAM file for vclock.

First seen in systemd-207-3-x86_64, also seen in systemd-207-5-x86_64 and
systemd-208-1-x86_64.

Also debug console (Alt-F9) not available until 08-1 (for me)

journalctl -f shows journalctl filling with this message, and not stopping
without hardware shutdown.

"...vclock[528]: pam_unix(vclock:auth):  auth could not identify password for
[ljohnson]"

bypassing PAM by adding vclock to /etc/pam.d/ is a workaround (attached)

occurs every shutdown/reboot.

Also unless umount /boot is issued before shutdown, it will be flagged for
fsck.
