Description Sevan Janiyan 2016-07-31 22:30:07 UTC
The published powerpc iso files do not appear to burn correctly on disk utility on OS X.
Confirmed on 10.3-RELEASE & 11-BETA3 powerpc iso using CD & DVD media with disk utility application on OS X.
With DVD media for example, 523.7MB is used up yet 0 directories & files on disk.
Comment 1 sysprint0 2016-08-05 05:02:32 UTC
I confirm the problem with the 10.3 PPC image
Burning the ISO on a Mac creates a bootable but empty disk with a subsequent kernel not found msg when booting.

Looking in the mail archives I found


Is the exact symptom but was answered with a failing capacitor !!

On my PPC Mac I managed to get the boot_only_iso to finally work after rebuilding the iso to a dmg

I have now run out DVD's to test this further.

There is some kind of extra layer in the PPC distribution iso that shouldn't be there.

Best regards

Adding re@, seems like the generated iso are still not burnable (according to the reported, including 11.0-RELEASE isos) from OSX, probably an incompatibility between the OSX burner and the format we are using, don't know. I have no OSX so I have no clue how to test

Note the details on space usage at the bottom of the screenshot.
Comment 5 sysprint0 2016-10-01 04:46:04 UTC

Could you provide details of your ISO creation method please ?
Program you use and flags you parse to it etc.

Your current method creates a perfectly bootable disk while the kernel layer and everything else required somehow is not found.

Do you create the ISO with the actual files present locally ?
Or do you use a truck load of symlinks during the creation ?

If you use symlinks then maybe 1 two many of them is interfering at the ISO's primary disk root directory.

Hope this helps in some way.

Kind regards from the South Pacific.

(In reply to sysprint0 from comment #5)

Examples scripts likely used to make the iso's, using stable/11 and releng/11.0 as examples:



In other words looking around in .../release/... for the context of interest likely has some of the material for how the release is made.

I'm using the stock images (xz compressed) from mirrors.

I fetch the archive, unxz, launch disk utility in OS X, press the burn button & point to the uncompressed .iso file.

system starts burning & commences with closing the session.

I'm using RW disks but have tried a full & quick erase in between.
Tried using CDRW & DVD+RW media.

Do not have problems burning other BSD iso images on said media using same burner.

"system starts burning & commences with closing the session."

system starts burning & commences to immediately closing the session.

Process is finished under a minute. Burner is not that fast. :)

Issue is definitely with Disk Utility.app on OS X
Just managed to burn the FreeBSD-12.0-CURRENT-powerpc-20161221-r310361-disc1.iso using cdrecord without issue.

Hi Sevan.
Good news you have found a work around.
My ppc laptop got trashed during a recent big earthquake and have only just got things going again.

To our FreeBSD friends.

The release ISO's you present look perfectly acceptable to OSX.  
They however produce an unusable disc when burned.
As below.
Note the free space.

(-options xsSgcvk)

The install data required is actually present.
It is getting confused by a finishing layer of some kind of unresolvable hard/soft symlinks 

Kind regards from the South Pacific.
