use Linux’s config script to flip settings?

[egberts]

To do a series of simple flipping of a single config while updating any and all config dependencies:

Single Option approach

./scripts/config --set-val CONFIG_OPTION y
./scripts/config --enable CONFIG_BRIDGE
./scripts/config --enable CONFIG_MODULES
./scripts/config --disable CONFIG_X25
./scripts/config --module CONFIG_NFT
make oldconfig
(updates dependencies; may prompt with new dependencies, but old deps silently goes away)

Multiple-File Merge approach

If you have several small snippets of .config-* files that you want to selectively merge into the main .config file, execute:

# Merge IP fragment CONFIG_ settings into the main .config file
./scripts/kconfig/merge_config.sh .config .config-fragment
# Merge  Notebook HW-specific CONFIG_ settings into main .config file
./scripts/kconfig/merge_config.sh .config .config-notebook-toshiba

# Auto-add/auto-remove CONFIG_ dependencies
make oldconfig

just a suggestion for ease of use and centralization of Kconfig settings.
