I'm afraid I don't have any useful thoughts. It's just a file. The log I've been keeping since October of 2014 has about 19,000 lines in it now and is just short of a megabyte. Gzip takes it down to 200K. So it's a pretty easy file to move about. The whole point is to ignore the log file itself, though, in daily use. I wouldn't want to be porting it around on a thumb drive every day. That being said, you can override the default location with the --directory option. Maybe this plus an alias so you don't have to type the whole path in every time. Maybe I've misunderstood your question.
