In my setup I need to rename the Linux system users man and bin because I need the usernames for humans. I'm using Ubuntu 12.04. I know that I have to change
/etc/shadow, etc. But when updating through apt, packages use the man user for their man pages, and those files would have false ownership then.
Is there an configuration option in Ubuntu where I can set how the manual user is called?
Same with the bin user: I don't know when it is used but I assume changing its name will mess something up.
