LGTM.

review: Approve

[Loïc Minier (lool)]

Is there something we should block on the hooks finishing? Like the unity8 session?

+# boot-hooks-emit - Triggers boot hooks
+# This job is used to trigger a variety of hooks at boot time on Touch devices
+
+# It does that through the "boot-hooks" event and the WHEN variable.
+# That variable can be "every-boot" or "new-version".
+# In the latter case, it's accompanied by two other variables,
+# OLD_BUILD and NEW_BUILD each containing a build ID.
