>Description:
When editing an MBR partition in sysinst, you can enter
a start sector 0..63, but then this is silently "corrected"
to start sector 64.
64 is probably the recommended alignment value, but this
doesn't enforce partition alignment as you can just
enter a start of sector 65 without "correction."
Another fault in the partition manager is that you
cannot add an MBR partition unless you delete one
partition (or all partitions?) first, then the
'Add a partition' menu entry appears.
When you add a new partition it gets "corrected" just
like when modifying an existing one.
>How-To-Repeat:
Try to install NetBSD in a MBR partition starting at sector 32.
