warn ftl: persistence error during setup: File I/O error

When starting the FTL server without a YAML file, the ftl .dat files are written/created by default on the location from where the executable is run.

The above error may occurs if there are not enough permissions to handle/modify/create the files used by the ftl and the default persistent server.

We recommend users to use a YAML file such as the below, in order to control the location of all ftl server files and logs, in which they can set the needed permissions in order to start and run the ftl server and services without any issue, see below my sample ftl YAML file
