[Bug 1335568] Re: Updates keep coming in while writable image is set

[Barry Warsaw]

This is basically a feature, not a bug.   system-image-cli is a developer tool, as is writable mode.  Developers are supposed to know what they're doing, so s-i-cli never changes its behavior based on writable mode and in fact never looks at /userdata/.writable_image.
You would have to pass `--build 0` to force a full update.

In IRC discussions, Sergio mentioned that it worked differently in
Saucy, where if writable mode was set, no updates would happen via the
system-settings ui.  If that behavior's changed, then it's a ui bug.
Note that system-image-dbus also does not look at
/userdata/.writable_image and does not change behavior based on writable
mode, however s-i-dbus is purely triggered through D-Bus activation,
which typically is only invoked by the systems-setting ui.
