Has anyone else tried making a USB 10.9 Install drive yet?

LionDiskmaker would not work.

Will try TargetDiskMode to get it on my MBA soon.

My normal Disk Utility method didn't produce a bootable USB volume either. Still trying things.

If you look inside the LionDiskMaker package you will notice it is built around a fairly simple, albeit long, applescript. Looking through the script you can see it was made specific to 10.7 and 10.8. It doesn't do a simple check for a minimum version. It makes sure it is a specific version. Because of that, it will not work without an update.

Same problem here. Burning a DVD didn't work either. I'm just going to install over ML until I can figure it out.

I hope Apple doesn't lock us out from doing clean installs.

There is a hidden file in installESD called Basesystem.dmg this is the boot image but not the install files, still trying to work out how they link together. But you can boot off of that image just not install.

Just like Mountain Lion, there is an alias for the Packages folder inside BastSystem.dmg. I think it is at /System/Library/Packages. You need to delete that alias and copy the Packages folder in InstallESD.dmg into its place.

EDIT: The alias is at /System/Installation/

For me it wouldn't install over ML. I had to format and do a clean install, possibly because of my DIY fusion drive. But no problems, I always back up :D.

Can I just restore the InstallESD.dmg on a USB or should I restore BaseSystem.dmg

During the attempt, did it inform you of the issue or did you loose data?
No it simply said that it could not install on the partition, so I knew something was wrong. I then did a time machine back up and erased the drive restored and then updated, I do not know what the issue was.
