From Fedora Project Wiki

Not sure I'd classify it as "very difficult" to change your real-name post-install; however, you have to be root to do it:

  1. System>Administration>Users and Groups
  2. double-click on account you wish to change
  3. enter new Real Name
  4. click OK

The decision to requite root access to change the real name makes sense in any multi-user context, to reduce opportunities for masquarading.
