Hi,
When configuring 2.6.1 with make menuconfig,
if I choose not to save my configuration changes,
I get this error:
puligny:~/build/linux-2.6.1% make menuconfig
make[1]: scripts/fixdep' is up to date.
scripts/kconfig/mconf arch/i386/Kconfig
#
# using defaults found in .config
#
Your kernel configuration changes were NOT saved.
make[1]: *** [menuconfig] Error 1
make: *** [menuconfig] Error 2
puligny:~/build/linux-2.6.1%
2.6.0 does not show such two error lines.
Best regards.
