+=== Configurable packages
+
+Some foundational packages like Busybox and uClibc can be configured
+with or without certain features. When writing Buildroot code that
+uses such packages, contributors may assume that the options enabled
+in the Buildroot-provided configurations are enabled. For example,
++package/busybox/busybox.config+ sets
++CONFIG_FEATURE_START_STOP_DAEMON_LONG_OPTIONS=y+, so init scripts
+meant for use with Busybox init may use +start-stop-daemon+ with long
+form options.
+
+People who use custom configurations that disable such default options
+are responsible for making sure that any relevant scripts/packages
+still work, and if not, adapting them accordingly. To follow the
+Busybox example above, disabling long form options will require
+replacing init scripts that use them (in an overlay).
