So, someone asked me(you know who you are) if it is possible to convert something like a computer types into a role, and yes that is possible and some times a pretty smart thing to do. If you have basically to kind of roles in your org and they are based on the fact that the computer is a Laptop (like a field engineer) or a Desktop (like a standard office user), well then it should work.
Converting Computer types into Roles:
In the Priorityline we have ByDesktop,ByLaptop,Role and Default
We use [ByDesktop] to return a value of yes/no and we store that in IsDesktop-Yes if it is a desktop and then we send it to a section with the name of IsDesktop-Yes. In the section [IsDesktop-True] we assign it the Property Role001 to ComputerIsDesktop. Now we can create a role in customsettings.ini, or we could create a Role in the MDTdatabase if you would like that instead and then assign all settings to that. In this case we will create a Role section called [ComputerIsDesktop] and in that role we will define all settings for that role, in this case it will be an application and then we repeat that story for a laptop.
Sample CustomSettings.ini file
Output from testing the customsettings.ini file and as you can see it has been assigned the role correctly and since it is a laptop it will get the laptop app.
