What you could actually do would be config UNIX bool "Unix domain sockets" if EMBEDDED default y since as the help text already says everything other than Y is expected to cause problems - and if people know they are in a space limited environment and really don't need it they'll still be able to disable it. As a bonus, making it a bool would allow to make the kernel image slightly smaller for everyone. cu Adrian -- "Is there not promise of rain?" Ling Tan asked suddenly out of the darkness.
