The installer is run in provision-mode in the init script
The installer is run as update-mode by supervisor by postinstall
Previously, we used to run the *same* installer code, which was
part of the base image, in both modes. However, after a reboot,
the old installer code is 'gone' and thus we start running the
newer installer code. This distinction is very subtle and this change
makes it more obvious.
If we want the same installer code to run in both modes, then we
really need to split out installer into a separate repository. This
can be done if required later.
This also makes it clear that announce is a feature of the provision
mode.
