No Fedora 13, em / etc / sudoers eu costumava ter uma linha:
Cmnd_Alias SOFTWARE=/usr/bin/yum
e, em seguida, para um usuário que teria o privilégio de instalar seus próprios pacotes RPM, uma entrada como:
david somehost=SOFTWARE
permitiria que eles executassem o yum sem problemas e instalassem o pacote.
Agora, atualizei para o F17 e isso quebra, assim como no exemplo a seguir tentando instalar o pacote "clang" (permissão negada).

O script Python /usr/lib64/python2.7/subprocess.py é legível pelo usuário (tem rw-r - r--).
Alguma dica?
