I am in the process of moving the content of an FC2 server to F7. In the process, I have to establish some new users with user and group numbers 501 and 502.

Unfortunately, F7 in its infinite wisdom decided to assign 501 to user "tclhttpd" and 502 to user "dbmail" (whatever they might be). (vigorously begging the question of WHY!!! in the world it did that...) :-(
They seem to be system account names, which in the past have ended up below 500, and I don't have those account names on my F7.
What web server and mail packages did you install ?


If I can't assign 501 and 502 to the users and groups they were on the FC2 machine, a LOT of permissions problems will be created in a fairly large and complex database and file structure.

What is the "right" way to assign different numbers to existing users like "tclhttpd" and "dbmail"?
usermod --help
I know I can just go in there and edit passwd and group but no doubt that will cause all sorts of unknown problems elsewhere, for resources and files that depend on 501 and 502 being assigned to "tclhttpd" and "dbmail". So, is there a "right" way that updates everything else to whatever new user numbers I assign?

I found a script a while ago to achieve the changing of userid and grpid on files/directories. This worked well in bringing the id's inline with another server. I can't find it at the moment.
