Comment 2 for bug 741890

this is an old bug, but its hugely mitigated in practice. There was a fix applied to process debug hooks/debug logs settings several months ago. Given the time for machine provisioning, its fairly straight forward to debug install/start hooks doing the logical thing.. ie.

juju bootstrap
juju deploy wordpress
juju debug-hooks wordpress/0

should work without issue.

The local provider being a bit faster to deploy (a few seconds), does require the debug-hooks command fairly soon after deploy, but that seems fairly minor.
