The PKG file
The first step to creating the installer is the PKG file. I installed Bosco the usual way, using the multi-platform installer. Then, I looked through the Bosco files (using a find command) to locate all of the instances of hard coded paths. They where located in the bosco.sh, bosco_setenv, and the condor_config files. I modified those to use the environment variable HOME.
Then I used PackageMaker from the auxiliary tools for Mac package available on the Mac developer page (free registration required). In PackageMaker, I opened the Bosco directory in the home directory.
I unchecked the 'Require admin authentication' because bosco will be installed in the user's home directory. After these simple steps, I built the installer and tested, everything worked!
A DMG is a disk image that is used for software distribution. The first step is to create the Bosco.dmg disk image using Mac's built-in Disk Utility.
After mounting the DMG, I copied the Bosco installer into the image. Then, I ran the command:
bless --folder /Volumes/Bosco --openfolder /Volumes/Bosco
This will cause the DMG to automatically open a window when mounting it.
Where to get this
The Bosco DMG makes it very easy to install Bosco on a Mac. The DMG is available on Dropbox, and will be put in production when a few more minor fixes are put in place.
