With initstepslew the foreground chronyd process doesn't exit until it
sets the clock or times out, so services started after the chronyd
service can be sure the clock is already set or it failed. But this is
not how 1.24 works, I think it was added later in 1.27.

The makestep directive just tells chronyd to step the clock on future
updates if the offset is too large as if you run "chronyc makestep".
If chronyd is giving up on resolving the names, adding makestep won't
change anything.
