At least for Ubuntu's builds the NSS modules seem to be ABI compatible between 2.32 and 2.33 (I didn't try 2.31 vs 2.32) but they are definitely not between 2.33 and 2.34. Cheers, mwh

In my case, systemd-resolved, systemd-timesyncd and colord. Using "systemctl daemon-reexec" fixes the issue. Unsure if there is really something to be fixed but as I didn't find anything about that, a bug report may help others. I suppose the problem is related to NSS.
