I'm going to try the alternatives first and at the same time email the 
author and the Debian maintainer of sfdisk and ask them what's up.

Our customers have complained about our boot times, so we've been 
tracking things down and fixing them.  We were doing two passes of 
mounting everything, one pass to figure out what was there, another to 
let the traditional 'mountall' init script do its work.  We were 
assuming that the mount times were constant and small.  But as the disks 
are getting bigger, the second mount is noticeable, so we're fixing 
that.  The first mount is definitely noticeable on the 2T machine, but 
we figure if we do our jobs right, people should rarely be rebooting anyway.
