CONFIG_EMBEDDED is _not_ a generic "advanced user" option, it's only for 
options that allow additional space savings.

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.

I'd rather much do in the Kconfig:

config UNIX
tristate "UNIX domain sockets" if I_KNOW_WHAT_I_AM_DOING # currently 
called CONFIG_EMBEDDED
bool "UNIX domain sockets"

allmodconfig: udev won`t start due to CONFIG_UNIX=m

2007-12-30 Thread devzero
Hi !

i build a kernel with allmodconfig and didn`t get my system to boot with that.

after some investigation i found that it was due to udev:

udevd[1226]: init_udev_socket: error getting socket: Address family not 
supported by protocol 

this was missing support UNIX DOMAIN SOCKETS at boot time.
easy - so i added unix.ko to my initrd.

but that didn`t make a difference. Still same error with udev.

seems, there are others who stepped into this trap and someone telling, unix 
domain sockets cannot be modular

since we have 1206 options set to "Y" anyway, would it make sense to remove 
module support for Unix Domain Sockets ?
opensuse103:/home/kernel/linux-2.6.23 # cat .config.allmodconfig |grep "=y" |wc 
-l
1206
opensuse103:/home/kernel/linux-2.6.23 # cat .config.allmodconfig |grep "=m" |wc 
-l
2098

i also came across this one:
