You mean the installboot usage, or something else?
I am not clear yet - I think installboot does everything exactly as
disklabel/newfs used to do before (at least I can't spot a difference).
As far as I remember, disklabel was the tool that used to install the
boot block. And disklabel merged the disk label structure with what was
in the primary bootstrap, and installed this as block 0. That worked.
And that is not what installboot does. But I must admit that my memory
is fuzzy, since I have not had to install boot blocks on my 8650 in a
long time. But I definitely did it at some point.
We have three possible errors (in historical order)
- the conversion to single bootblock introduced a bug for disks with
the first few sectors zeroed
No. The single boot block itself is fine and working.
- the moving of the bootstrap installation into installboot introduced
Yes. installboot does not install the boot block at the proper place.
- the firmware/boot procedure used by simh has a bug
No. Installing the correct boot block allows simh to boot fine. simh
works (in this detail) just like a real 8650.
