Comment 40 for bug 1240848

Why not just disable this logging behaviour by default? No one knows about ~/.cache/upstart until it fills their disk and breaks their system (if they are savvy enough to find the problem log file).

The handful of power users that might occasionally need this logging behaviour can work out how to switch it on. In the mean time, not all of the users being impacted when it fills the disk will be able to work out what needs to be done about it.
