/dev is a tmpfs, that is, it is not stored on disk, but on RAM. This is due to the small and volatile nature of the /dev tree when running under udev. shm stands for SHared Memory, and I don't know specifically why it's there. It seems like it is a way of passing data between applications via shm_* glibc calls. -- Felipe Sateler -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
