MacOSX: Arrange icons in a dmg
From Apache OpenOffice Wiki
This article is a step by step instruction how to re-arrange the icons in a disk image after e.g. a version bump.
1. Convert the disk image you want to modify to an uncompressed format. To avoid any user specific data, change to the /tmp directory first:
# cd /tmp # hdiutil convert -format UDRW -o temp.dmg OOo_2.4.0_080125_MacOSXIntel_install.dmg
2. Mount the disk image, free disk space and make .DS_Store file writeable
# hdiutil resize -size 500m temp.dmg # hdiutil attach temp.dmg # chmod +w /Volumes/OpenOffice/.DS_Store
3. Re-arrange the icons. If you need to re-set the background image, select "Show View Options" from the context menu, chose Background: Picture -> Select, then press Shift-Cmd-G to open the folder /Volumes/OpenOffice/.background and select background.png.
4. Eject the disk image to force Finder to write the DS_Store file
5. Re-mount the disk image and grab the DS_Store file:
# cp /Volumes/OpenOffice/.DS_Store ./DS_Store
