Name
UNIX — Unix domain sockets
Description
If you say yes here, you will include support for Unix domain sockets;
sockets are the standard Unix mechanism for establishing and accessing
network connections. Many commonly used programs such as the X Window
System, syslog, and udev use these sockets even if your machine is not
connected to any network. Unless you are working on an embedded system
or something similar, you therefore definitely want to say yes here.
