Where did you saw that?

And why are you giving fedora yum as an example?

Any way, related info may be
man sudoers
or
man visudo

I do not recommend sudo without password (of course, I think) for every command
Nevertheless, I use something like that for the rsync command on my
backuppc configuration

Check the NOPASSWD option on the sudoers man

I have:
$ sudo cat /etc/sudoers
[sudo] password for lpaulo:
  # /etc/sudoers
  Host_Alias	LOCAL=desktop.xxx.pt
  backuppc LOCAL=NOPASSWD: /usr/bin/rsync --server --sender *
  [...]

PS: maybe point 1 of John DeCarlo answer is what you are looking for?
