This is a followup to Randy Bentson's article about daemons running as root. It is true that programs run by superuser can not set lock files by simply trying to create a file with no permissions. Look at the lock mechanisms used in uucico. The locking mechanism there is to link to a file. If the file exists, the link call will fail, even for superuser.
