It basically means that, if you have it in your /etc/fstab file, when the system boots, it will make a RAMdisk (in DOS terms) out of your 8Meg of RAM, thereby giving you less memory to play use. On systems with a large amount of "real" RAM, it is generally used for /tmp, speeding up some programs by not requiring temporary files to have to be written to a "real" hard drive > Also, in the config file, there are references to 'tun' & 'ijppp'. > Two of the lines were hashed out in the distribution package.

Since I only use ijppp, I've disabled ppp, but, I believe, the ppp device is for when you have users dialing into your machine to connect using ppp... Marc G.
