6.3.3 Beta 3 working O.K. but unexpected built-in accounts

[StephenB]

It is working ok for me so far. I am seeing a lot of built-in accounts that I don't remember seeing before,
cat /etc/passwd gives

My guess is that these can't be used for user account names. If so they probably need to be documented as reserved someplace (some seem likely choices for users)

I have 6.2.2 installed, and the password list is exactly the same.

[StephenB]

Good to know. can a 6.1.x user check it too?

[Skywalker]

These haven't changed, going back to 6.0.0.

[StephenB]

I can imagine people trying to set up a "ReadyNAS", "games", or "ftp" account (or possibly even "media").

The current error message if you try that is ok, but it would be nicer to say "reserved" rather than "exists or is reserved".
