#10 typo in "$>make -f local.mk kconfig"

[Toralf Förster]

n22 /usr/src/aufs # make -f local.mk kconfig
copy ./fs/aufs25 as fs/aufs and ./include to your linux kernel source tree.
add 'obj-$(CONFIG_AUFS) += aufs/' to linux/fs/Makefile.
add 'source "fs/aufs25/Kconfig"' to linux/fs/Kconfig.

This works better

'source "fs/aufs/Kconfig"'

:-)

BTW I prefer to create symbolic links over copying the directory and the include file respectively.
