Have you employed the useradd command and seen what exactly it does in a system? There are plenty of options to control what it does and therefore what impact it will have on a system. It doesn't always have to create a user's home directory, but it can, and that all depends on how you use the command.

useradd(8) - web based man page, however you should check the version you have on your system and determine what options it supports.

I don't remember all of them. Add user fred, then

Code:

ls -lA /home/fred

and see.

Everything you put into '/etc/skel' will be copy into its HOME when you create a new user.

Not necessarily. e.g. on multiboot systems where /home is a filesystem shared among multiple installations, creation of a new user named e.g. user2 will copy nothing from /etc/skel if /home/user2 already exists.

there's bound to be some entries in system files/folders too.

Yes, true. Or if the username have existed and have been deleted, but its HOME remains and you want to create an user with this same HOME. But both cases are kind of unusual.
