reroot is covered in docs (link) -- although it says it's faster than a reboot it still took a few mins.
To perform a reroot, choose option r when triggering a reboot from the terminal menu.
Since everything in my stack is automated (no human touch where we can help it), I just made a simple php script that triggers like this (php) and it's called through our automation engine:
require_once("functions.inc");
system_reboot_sync(true);
the true in system_reboot_sync(true) tells it to do a reroot instead of a reboot. It's not documented, but I found it in the source code here
