Running `debops run wordpress` without `-l` option causes swapfile error

[Kairixir]

Task TASK [debops.debops.swapfile : Enable swap files] fails for the second domain in order.

I believe it has to do something with mutex due to extended log when -vvvv option is used. I believe it is because DebOps swapfile role does not expect to run two hosts on a single server.

I won't post the full log, since I have not scanned it for sensitive information. Won't do it now. To see the issue use commit 95c345f3f36bf9947cc7e7cda604c86ba4e0ed15, setup the environment, and run debops run wordpress --tags role::swapfile -vvvv. Temp fix is to run one host after another using -l option.

Minimal example could be to run two hosts on a single server with swapfile role. Have not tested.
