I've had a lot of arguments about file permissions, and I want to know if there's any difference at all between user vs. group permissions. For example:
If I have a file with two possible configurations:
-rw-rw---- 1 root www-data 5 Jan 6 10:44 test
-rw-rw---- 1 www-data www-data 5 Jan 6 10:44 test
If I change ownership to the second one, is www-data gaining any privileges that it didn't have when it could only access the file via group permissions?
