Munki really is brilliant. From the user’s end, it is basically invisible, installing software when the computers are sitting logged out and never bothering anyone. From the admin side, it is super quick to import a package file and super easy to add it to the list of files to be installed. This week alone I have been able to push out three different installs, confident that, by the next day, they will be installed on all the machines.
The only problem with it is that the admin backend is not hugely user-friendly, relying on setting up your own webserver, typing stuff into Terminal and editing a .plist file of software to be installed. I would love it if someone might perhaps consider building a beautiful and simple GUI backend too. Anyone offering?
