Unix domain sockets have a severe limitation that the path must be a maximum 108 characters. Currently the UDS is created in the relative data directory, which can be a lot longer, depending on the user's setup.
By default mysql uses the /tmp directory to create UDS.
Introducing a socketDir attribute would allow users to override the UDS location. The value of socketDir should default to dataDir to maintain backward compatibility.
