Task "Write gossip encryption key locally for use with new servers" is flakey

[Nik Reiman]

We often see this task fail in our CI runs, but since it has the no_log property, we don't have logging output that might be useful in helping to figure out why.

Is anyone else experiencing this? Also, it might be nice to have a var to control logging output for such tasks rather than assuming no_log: true.
