I'm using MAAS 2.3.5 to provision my bare metal host with Ubuntu 18.04 - bionic. when i log in to my newly provisioned host i'm noticing that a swap file exist.
none of my preeseeds file (curtin_userdata files) contains anything related to swap configuration. When checking the installation output of my node in MAAS web ui i see that indeed the swap file was set during the curtin installation (node installation logs snippet bellow).
My question is: where does this swap file settings is configured? Is it MAAS defaults? Is it curtin defaults?
Installation log output:
