Everyone wants to have users download a small .dmg file from their website. Opening the dmg pops up a window showing a pretty background, the application's icon, and an alias file to the /Applications directory.
Finder in 10.6 creates non-backward compatible .DS_Store files, so to get the positioning and background image, you need to create a dummy dmg by hand on 10.5, copy its .DS_Store, and save it for copying into your production dmg.
No-one wants their dmg to have a .Trashes directory, and no-one wants the mounted image to have free space -- it's just wasteful, and it feels unprofessional. The key to creating just such a dmg is to populate a local directory with everything you want in your dmg, use hdituil to makehybrid from it, and then convert to the desired format (probably UDBZ format with -imagekey bzip2-level=9 for maximum compression).
If you have an SLA that you want to display, you can unflatten, add the rtf SLAs using Rainer Brockerhoff's AddLicense tool, and then flatten the dmg again.

Creating a DMG with an icon and background image
[Posted with permission from my client.]
Our Release mode build is designed to package up the final app bundle into a dmg. We wanted to make a nice user experience, similar to the images of Google Chrome and Firefox, so we added an alias to /Applications and set the alias' name to " ".
We use an applescript to set the position and size of the icons in icon view, and also to set the background image. However, we could not figure out how to set the icon for the mounted volume in Finder's sidebar. I knew that it involed .VolumeIcon.icns, but that was insufficient.
After much searching, we realized that we had to set extended Finder attributes for the volume's root directory, but couldn't figure out how to do so from the shell / applescript. Finally, we found xattr, but there was no documentation to indicate what names or attributes to use. However, Google Chrome and Firefox both had the same set of 32 4-byte hex flags, so we simply copied them.
Solution: with read/write dmg mounted (and a disk name of VOLUME_NAME), use the following command from the Terminal (or shell script):
UPDATE:
There is a much more intuitive interface:

SetFile -a C "/Volumes/${VOLUME_NAME}".
