Is it possible to quasi-rotate minimserver.log?

[simoncn]

The debug log output is intended for debugging only. You can use it for other purposes but this not a supported feature of MinimServer. It is not practical to split this output into different types of output going to different destinations. Fortunately there are tools such as grep that can do this.

If you want each log line to have a full date and time, you can set the .logPrefix property to dateTime. For a list of supported .logPrefix values, see this section.

Edit: The above statement isn't correct. See this post.
