macos - How do I get rid of com.apple.launchd.peruser errors in my log?

I'm getting repeated errors in my console log that look (basically) like this:

10-09-29 10:06:08 AM com.apple.launchd[1] (com.apple.launchd.peruser.501[51581]) getpwuid("501") failed
10-09-29 10:06:08 AM com.apple.launchd[1] (com.apple.launchd.peruser.501[51581]) Exited with exit code: 1

This machine was set up using the migration assistant, from a machine where my UID was 501, but here it's 505. I have the same username and group set, of course, but...

So, where is this peruser launchd tool configured, so that I can disable the daemons that are causing this error message?
