Clarify actions of Alpine Linux install script
@@ -15,11 +15,20 @@ The bundled `build.sh` script can be used to configure and build finit:
alpine:~# cd finit
alpine:~/finit# ./contrib/alpine/build.sh

+Then run the `install.sh` script to install all files, including the
+sample `finit.conf` and `finit.d/*.conf` files. More on that below.

alpine:~/finit# ./contrib/alpine/install.sh
-The installation skips `/sbin/init`, because it already exists, and
-Alpine is hard coded to use it. So you have to change the symlink
-yourself to point to `finit` instead of `/bin/busybox`.
+The install script is non-destructive by default, you have to answer
+*Yes* twice to set up Finit as the system default init. Pay close
+attention to the last question:
+
+ *** Install Finit as the system default Init (y/N)?
+
+If you answer `No`, simply by pressing enter, you can change the symlink
+yourself later on, to point to `finit` instead of `/bin/busybox`:
alpine:~/finit# cd /sbin
alpine:/sbin# rm init
