I want to install centos 4.4 in a CF card and use a ram disk for operations. It means no hard disk attached to the computer. The machine will only run an antispam antivirus gateway. What documents can I read to make /var and /tmp sit on a ram disk and boot the operating system in read write and switch to read only after booting? thanks, -- ------------------------------------------------------------ Erick Perez Panama Sistemas Integradores de Telefonia IP y Soluciones Para Centros de Datos Panama, Republica de Panama Cel Panama. +(507) 6694-4780 ------------------------------------------------------------
