I came up with the same idea, and it does in fact, avoid the issue. We needn't be using journaled on this disk image anyway. -----Original Message----- From: Soren Spies [mailto:sspies@apple.com] Sent: Friday, May 08, 2009 11:19 PM To: Nathan Herring Cc: Dev Darwin Subject: Re: Use of hdiutil in a launchdaemon?

In this particular case, it looks like you're running into the fact that we use 'diskutil' to disable journaling during the copy phase of creating a disk image from a source folder. A workaround might be to pass '-fs HFS+' to 'hdiutil' instead of letting it default to matching the source filesystem (which sounds like it is HFS+J). -- Soren Spies CoreOS::DiskImages _______________________________________________ Do not post admin requests to the list.

Thoughts? This looks like a "I spent sunday afternoon surfing, and found these cool projects. Apple should implement them in it's OS." I don't think Apple is really going for the hardcore datacenter system's that 'Zones' is aimed at. And businesses are still wary of putting Apple hardware in their datacenters. For an example, see complaints about the disappearance with no notice of Apples XRaid hardware. Yes, you can still buy parts for them, but it was literally, one day it was present on the Apple Store web site, the next day, gone, with just a "Apple recommends some third-party RAID system now". Why put Sun Grid Engine into the kernel? It looks like something an individual could possibly port (but I haven't looked at the actual code), and it doesn't appear to need to be embedded into the kernel in any significant way. I would bet it is extremely unlikely Apple would migrate to L4, but they might consider using some of the concepts from the project to make their kernel better. As I am Steve Jobs silent partner at Apple, this is Apple's official word on the subject. This email sent to site_archiver(a)lists.apple.com
