Not sure if this is related but.... With regard to tmp directories, I'd like to see two things as default: 1. Each user should have there own ~/tmp space which only they can access. This could be used for the users agent sockets, but also just for general files that they would put in /tmp. This would give a better level of privacy (for whatever reason, but maybe simply so they don't have to think about the privacy implications of putting things in a publically accessible /tmp folder) 2. The system should have a general 'shared' folder that appears as a folder in each users home directory, but where any files placed there can be accessed by anyone else. This folder shouldn't delete files after a period like /tmp does, and if shouldn't cause problems with ownership (a security issue maybe). My father, who worked at the Bureau of Meteorology in Melbourne and who has use Unix as part of that always comments that one of the biggest issues he had was being able to simply share files with others without having to contact a sysadmin just to get a 'shared folder' set up. My wife concurs with him, thinking it's mad that she has to put important files in /tmp just to be able to share them, and while I could do something about this, the reality is that they would both like it to be done without having to ask anyone. (It's a small sample size, but I'm sure others have heard similar comments. 8-] ) Thoughts (and beratings ;-] ) R. -- "It's a fine line between denial and faith.
