The installation program told me the log had been saved
to /tmp/pc-sysinstall.log, and showed the contents of that file. It
contains a copy of the configuration:

[...]

Unfortunately it's not so simple because gpart apparently requires that
the start sector for the MBR scheme be divisable by 63. 258048 should
work I think. It won't affect non-4k disks - Windows has been using an
offset of around 1MB since Vista
(http://msdn.microsoft.com/en-us/library/dd758814%28SQL.100%29.aspx).
