I have Guix on an X200 (basically the same as yours) and I can confirm, it's slow. I don't think it's related to ntpd. I see the same warnings but the system displays the login prompt before they are resolved. Generally, the issue is that the Shepherd is not optimized to the degree that systemd is, and that these old Thinkpads (sold in 2008) are really slow by contemporary standards. One of the early selling points of systemd was that it reduced boot times from being measured in minutes, which used to be typical, to seconds. Now systemd is the standard, and minutes-long booting seems incredibly and unreasonably slow.
