I do not know how Fedora works, but on Kubuntu the user created when 
installing the SO is also 'root': one need only to use 'sudo...'. After 
typing the password it 'remains active'  for about 15 minute. This mean 
that if I use 'sudo less foo.txt' when that pass. is active I do not 
need to retype it, and, as 'root', I can read that file. But if I open a 
new shell, in which the passwd is not yet 'active', trying 'sudo 
less...' asks for the passwd, which looks right to me.

Why 'root' should read, for example, private mails of the other simple 
users of that PC?


Cheers,
Angelo.
