You should read my follow-up email too that suggested changing
the systemd script.

For some reason this is causing the final two tee's to be created
as children of debian/tests/timedated rather than the bash shell.
This is because of the same optimisation that dash also has, where it
tries to avoid creating a subshell for the last command in a list when
it can just exec() without a fork() instead. A minimal example without
an explicit exec is
bash -c 'dash -c ": & wait" <(sleep 1d)'
