Comment 15 for bug 457702

Please note that in Lucid, a upstart script exists for both reboot and shutdown that triggers a forced shutdown/reboot and bypass the regular shutdown sequence.

These two scripts issues a "sync" then reboot or shutdown depending on the runlevel.
/etc/init.d/sendsigs will then never be called at shutdown or reboot making updating the process blacklist useless in this case.

That new LTSP including updated upstart jobs and other upstream fixes will be uploaded later today.
