Saber si tu computador tiene solo software libre instalado

Si no lo sabes, ahora con una aplicación llamada vrms (”Virtual Richard M. Stallman”) podrás conocer el número de paquetes instalados que no son libres e incluso el porcentaje. Para ello tenemos que instalarlo lo primero:

# apt-get install vrms

Y después ejecutar como root el comando:

# vrms

Lo que nos devolverá algo parecido a esto:

juaramir@mefisto:~$ sudo vrms

juaramir@mefisto:~$ 

Bueno Aunque tengo 29 paquetes no libres de 1738 en total que equivalen al 1,7% del total no esta tan mal, aunque ahora que conozco este comando procurare disminuir ese 1,7% al mínimo.
