I'd like to auto mount my dmg file which represent disk image with single HFS+ partition upon every boot. is it possible through autofs ? do I have to set the location of the dmg file in any configuration file (/etc/...)

You can simply add the .dmg file to your Login Items in: System Preferences > Users & Groups > (you) > Login Items

The .dmg file will then automatically be mounted when you login.

Update to address comment: "Is there any API to add item to login items programmatically?"

One programatic way I know of, it can be done with AppleScript:

Example AppleScript code:

tell application "System Events" to ¬
    make new login item with properties ¬
        {name:"Mount DMG", path:"/path/to/filename.dmg", hidden:true}
  • Change "Mount DMG" and "/path/to/filename.dmg" as appropriate.

It can also be done from Terminal using, using the osascript command, with the same AppleScript command:

osascript -e 'tell application "System Events" to make new login item with properties {name:"Mount DMG", path:"/path/to/filename.dmg", hidden:true}'
  • Change "Mount DMG" and "/path/to/filename.dmg" as appropriate.
