I have an iMac with the HD split into two equal size partitions. Both partitions are bootable with Snow Leopard. I then start-up partition 1 with an admin user account.
I want to create a disk image of partition 2 and save the .dmg file on partition 1. I have to do this remotely from a box running Linux.
The shell command I'm using is
ssh <username>@<ipaddress> "echo password | sudo -S hdiutil create -puppetstrings -srcfolder /Volumes/Part2 /Users/Shared/image.dmg"
When I run the command from the remote shell it consistently dies around 98%, but when I run the hdiutil from / of partition 1 on the box hosting partition 2, everything works as expected.
I've been able to run other hdiutil commands from the remote shell. I'm only having a problem with the create verb.
I don't believe it's a network issue because it always dies in the same place. I'm puzzled why the same command would behave differently when executed from a remote shell.

Now I just had it die on the local box. I'm now thinking it has something to do with the puppetstrings option or the path provided before the image name. When I successfully ran the command I didn't have puppetstrings or a path. I suspect puppetstrings because the numbers are off. The command dies with the console showing 78.651413 four times before going to -1.000000. Plus 78% isn't an accurate reflection of the new image file size compared to the expected image file size. – ChrisP – 2010-12-14T21:10:33.823
There is something strange with puppetstrings. Normally I would kill the script when I see the console display percent: -1.000000 because the man doc says that is an error code. This time I was doing a different task and didn't kill the script and when I came back I saw the image had been successfully created. So I was getting thrown off by the feedback from puppetstrings because when I don't have that feedback I just wait for the shell to come back without killing the script. Anyone else use the puppetstrings option with the create verb? – ChrisP – 2010-12-14T21:49:33.620
As per here, a value of
