Hey!

After upgrading to libc6 2.32-1, some services are unable to restart.
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.
