Q: bitbake -c savedefconfig overwrites current configuration Yocto environment for an ARM embedded board.
Following these instructions I'm having hard time to change the kenerl configuration.
Basically I did:


*

*bitbake -c menuconfig virtual/kernel

*enabled a new driver (i.e. PPP)

*save

*check new the items in .config

*bitbake -c savedefconfig virtual/kernel

*now both defconfig and .config don't have the PPP module anymore

*even more: entering again the menuconfig it is disabled


Why it does not work as expected?
