No, 'sudo' es un comando nada mas. Es una versión de 'switch user', la
ventaja es que 'sudo' lo puedes configurar con privilegios para realizar
tareas administrativas en el sistema. Pero es una larga historia... por
lo de los permisos en Unix.
'sudo' es muy recomendable de usar porque en lugar utilizar el usuario
'root' en un sistema Linux, 'sudo' te ayuda con ciertos comandos que
requieren de autorización del administrador del sistema. A veces con tan
solo tu login y el password.
Evita usar root porque si no configuras las cosas de acuerdo a ciertos
parámetros establecidos, de pronto te puedes ver obligado a re-instalar
el sistema. Sobre todo con los parámetros en XORG.conf.
Suerte,

SUDO(8) MAINTENANCE COMMANDS
SUDO(8)
NAME
sudo, sudoedit - execute a command as another user
SYNOPSIS
sudo -h | -K | -k | -L | -V
sudo -v [-AknS] [-p prompt]
sudo -l[l] [-AknS] [-g groupname|#gid] [-p prompt] [-U username]
[-u username|#uid] [command]
sudo [-AbEHnPS] [-C fd] [-g groupname|#gid] [-p prompt] [-r role]
[-t type] [-u username|#uid] [VAR=value] [-i | -s] [command]
sudoedit [-AnS] [-C fd] [-g groupname|#gid] [-p prompt]
[-u username|#uid] file ...
DESCRIPTION
sudo allows a permitted user to execute a command as the
superuser or
another user, as specified in the sudoers file. The real and
effective
uid and gid are set to match those of the target user as
specified in
the passwd file and the group vector is initialized based on the
group
file (unless the -P option was specified). If the invoking user
is
root or if the target user is the same as the invoking user, no
password is required. Otherwise, sudo requires that users
authenticate
themselves with a password by default (NOTE: in the default
configuration this is the user's password, not the root
password).
Once a user has been authenticated, a timestamp is updated and
the user
may then use sudo without a password for a short period of time
(5
minutes unless overridden in sudoers).
