Hi Simon, Thanks for the quick reply...
The install would have used whatever the default was as of the
DEVELOPMENT snapshot of just a few days ago.
DFLY was happy cooperating with the (at the time) DFLY, Slackware,
OpenBSD, NetBSD and each booted fine off the new DFLY bootloader.
FreeBSD 8- December snapshot was used to change the type of the second
slice, sub-partition it, then install itself to replace Linux.
Bad move, as along the way it screwed the hammerfs-bootable DFLY somehow.
fdisk sees what was expected.
The other three OS'en still boot and run nomally.
Selecting DFLY (F1) returns 'invalid partition'
What I get with either disklabel or disklabel64 off the DFLY
Live/Install CD is:
'bad pack magic number'
Attempts to edit the label give:
'Operation not supported by device'
Now - IF I knew what bits or bytes to change and where, I'm happy to go
after it with a hex editor... or dd. or whatever.
But I had not made a disklabel copy, so ....
you could post the output of
dd if=/dev/adXXsYY count=4 | hd
for us to debug. Alternatively, you can try killing the disklabel with
dd if=/dev/zero of=/dev/adXXsYY count=4
and then re-creating it. it basically has to read:
a: * 0 HAMMER
b: $SWAPSIZE * swap
where swapsize is the value you entered in the installer. The default
value depends on your memory size and is
I've gotten into disklabel -e mode with NetBSD.
Not going to change anything just yet, but rather write what it sees, do
the same with OpenBSD and FreeBSD (perhaps even a Linux).
Will post those as well as the dd output 'shortly'.
