I agree with all of you. /dev/shm is widely available, and is a filesystem of the desired type. /var is intended for this kind of data, and /var/run seems intuitively the right location. But /dev as well as /var are often mountpoints. So to use those locations would introduce more mountpoints that will need special care early in the startup scripts. And mounting them before running fsck is a problem. All of those thoughts is what lead me to the suggestion of a new directory or symlink in the root. You can point it anywhere you want mtab. And you don't need to mount any filesystems before the symlink can be used. A symlink in the other direction would not work that well. -- Kasper Dupont -- der bruger for meget tid p? usenet.
