GMRS Image for RPi question

[WROZ250]

I downloaded the GMRS img file that was posted a few months back.  However, I have a question...

Is this RPi image really all that different from the ones used by Amateur Radio's Allstar image or, are there just a few network related parameter changes in key configuration files?

I ask, because after recently building an Allstar repeater with the RPI 3B+, it seems a relatively minor effort to change the network servers in the config files from a working Allstar config system to those used for GMRS.  Seems like duplicating/cloning a working image and simply changing the required parameters rather than start a new build from scratch would be easier.

Just curious.

Thats a question for @rdunajewski

There are significant differences and the specific version of the software needs to be correct as well.

Could you go through and figure out the required changes and make them on the correct release version of the software if you KNEW Asterisk fairly well, yes, to a point. 

Will you spend more time going through all that to modify the config files, DNS entries and all the rest needed to get an Allstar version modded to operate on the GMRS network.  And there is NO support for modded versions from the system admin.  They support the available release.  And they know quickly if it's a modded version or the supported image.  You have to image a drive to get this to work, no way around that.  So why go through all the effort of getting a non-supported version, then needing to modify the heck out of it so it will work and be on your own if there are problems.  Just DL the correct version and configure it per the provided directions.  If you are worried about the audio level settings since you already have them configured for a current repeater then go in and document that info and write it down.  It will not change with the new version.
