Have it as tmpfs, simplifies the way these are purged on startup (rc.sysinit), in a way that removes the need to run "find, rm" on them. Particularly in /tmp, where the removal of these files, can be dangerous. But today, the command "rm" progress, not left behind quite a number of vulnerabilities. For example: rm -rf /tmp/.* (that is used in rc.sysinit) in the old days it was dangerous, as it descended recursively deleting the parent directory. Today rm refused to use the forms "rm- r ." and "rm -r ..' and similars and ignore these special directories. This also are applied to the /var/lock that have 1777 perms like /tmp. At least, this is the use that I give. Other people may give it another utility.
