Run script at first login

What is the best way to add a script to MDS which will run on first login and only once?

After finishing the MDS deployment I need to run a custom script after login which depends on internet connectivity to install homebrew and perform other customizations.

Regards,

We are adding that in. I expect it to be in 1.9. You can do it yourself if you know how to create a package with a self-deleting launchagent. Also, let me know if you purchased a support contract. That will help escalate it.
