 <p> Since these scripts, configuration files and other tools are
     custom-designed for a specific device, Busybox mailing list is usually
     a wrong place to ask about inner workings of such a device.
+</p>
+<p> For a specific example shown above, the answers most likely would
+    look like this:
+</p>
+<p> "Can I enable FTP?" - "We don't know whether Foomatic-9000 firmware
+    comes with Busbox binary with enabled ftpd applet. (If you have access
+    to shell prompt, try running "busybox ftpd --help"). If it does,
+    you probably will be able to enable it. Unfortunately, we don't know
+    how Foomatic-9000 firmware manages starting and stopping of various
+    services (in case they already have ftpd sevice and it is just disabled),
+    or how to create and enable a new service on Foomatic-9000 (if they dont).
+    Try googling for it."
+</p>
+<p>
+    "Can I enable SCP?" - "Busybox-1.23.4 does not have scp applet.
+    However, Foomatic-9000 might have scp installed (say, if they have
+    dropbear installed), and it may be possible to enable it. If not,
+    it may be possible to build and install your own scp tool.
+    Try googling for it."
+</p>
+<p> "If I edit a file on the device, I can't save it, I get
+    'filesystem is read only' error. How can I save a changed file?" -
+    "Most embedded devices use flash-based filesystems, and often these
+    filesystems are configured to read-only mode in normal operation.
+    In order to modify some files, you need to find out how to switch
+    the filesystem into read-write mode. Note that sometimes embedded
+    devices use read-only filesystem formats such as cramfs, and therefore
+    in order to replace or add even a single file (such as a new, or
+    an additional Busybox binary), you need to re-create and write out
+    the entire filesystem image. This operation is not simple for
+    inexperienced users and may permanently disable your device if done
+    incorrectly."
+</p>
+<p>
     You are better off googling for a forum where users of this particular
     device discuss their findings about inner workings of the device,
     and joining it.
