Do the UNIX file permissions mean anything anymore?

The files contained within your afs home directory use both AFS and UNIX file permissions. The only UNIX (chmod) permissions which are still applicable under AFS, however, are the permissions for the owner. UNIX permissions on directories are not used. Your temporary files (those found in /tmp and /usr/tmp) are in local UNIX file space. Only the UNIX file privileges apply here. That is why the umask variable in your .cshrc is still important. The default .cshrc file has umask set to 077, which gives no file permissions to other users. For more info on UNIX permissions and AFS, read the Advanced AFS Page.
