The mechanism should be identical to when you use the Shut down or Reboot buttons in the Linode Manager (or the automated shutdowns during a migration or upgrade, for that matter). So if you wanted, you could run a test in advance when convenient on your own schedule to ensure your Linode will do the right thing during such a shutdown/reboot cycle. But yes, for me such shutdowns (whether manually by me or automatically by Linode) has always been a graceful shutdown assuming the guest was operating properly in the first place.

When using Debian under KVM and virt-manager at home, I need the acpi-support-base and acpid packages to be installed so that the "shutdown" menu works. Surprisingly, this package was not installed by default on my first linode Debian 7 deployment. Is Xen different about this?
I'm guessing here, as I don't know for sure, but Linode uses Xen PV for its guests, so I expect the PV drivers are shutting down the guest from within the guest itself. It's not simulating an external hardware signal to generic drivers; rather the Xen aware drivers execute a shutdown on your behalf.
