I know this probably falls under "not supported" but this is something that has works for us for years.
We image our Macs using ghost. It's not that hard, you just use the ghostcast server and the image goes and goes fast! But this year it failed over and over until i tried an image created last year on the old ghost server (2.5) and it worked perfectly. To further the test, i re-captured my image on the old server with the old ghost client and then put the image on a Mac and it worked. i'll try to explain the pass/fails below.
image(X) = image captured on X version of Ghost (2.5/3.0) (version of ghost on bootable USB)
Server(X) = image captured on X server version (2.5/3)
Capture/restore
image3, server3 = fail regardless of restore
image2.5, server3 = fail regardless of restore
image3, server 2.5 = fail regardless of restore
image2.5 server 2.5 = success when restore on old ghost server with old client
When i tried to restore an old image from the new ghostcast server i still got a fail.
SO what this all comes down to is if you're having problems with the new ghost, try the old ghost client with the old ghost server and see how that goes. In full disclosure, i have ZERO problems on Dells, this is just a Mac problem which is why i'm sure people wont care. Let me know if i can expand on this more, i'm just throwing it out here quick when i have some time.
