// 1. new Batphone APK is installed, but prior servald.conf is not overwritten because it
// comes in serval.zip;
// 2. new Batphone is started, which calls JNI "stop" command, which reads the old servald.conf
// into memory buffer;
// 3. new Batphone unpacks serval.zip, overwriting servald.conf with new version;
// 4. new Batphone calls JNI "config set rhizome.enable 1", which sets the "rhizome.enable"
// config option in the existing memory buffer and overwrites servald.conf;
// Bingo, the old version of servald.conf is what remains. This kludge intervenes in step 4, by
// reading the new servald.conf into the memory buffer before applying the "rhizome.enable" set
// value and overwriting.
