Robert,

Excellent information and succinct.  Thank you for this.  This gives me great 
assurance of the supportability and maintainability of the Beaglebone Black 
Debian image as an OS baseline.  You pretty much confirmed what I hoped was the 
case.

Debian almost dropped "armel" during Buster development cycle, it days going 
forward is very limited..

The BeagleBone Debian Images is not a port of Debian..  Instead, we start with 
a pure Debian install, then add our Custom Kernel, Custom u-boot and any 
packages either not in Debian, or backported from
Stable+1..

Sure, let's look at Debian's product lifecycle:
https://wiki.debian.org/DebianReleases

Version  Code name  Release date End of life date EOL LTS EOL ELTS

10 Buster  2019-07-06 ~2022
9   Stretch 2017-06-17 ~2020 ~2022
8   Jessie  2015-04-25  2018-06-17 ~2020-06-30

Then lets look at this email i sent out, detailing my plan for Jessie and 
Stretch:

This can be easily explained by looking at our /etc/apt/sources.list

debian@BeagleBoard-X15:~$ cat /etc/apt/sources.list deb

http://deb.debian.org/debian buster main contrib non-free
