Yes, we are working on a cloud-init patch to allow cloud-init to manage
the setting. The default will be to disable pipelining, but will allow
users who wish to configure the manually to do so. We expect to SRU this
patch and then back-port it for all version of Ubuntu that are affected
(Hardy, Lucid, Maverick, Natty, Oneiric and Precise).
