Why does end of life matter to a machine controller?
Once you have a kernel/motherboard/distro combination that woks,
I wouldn't want to upgrade the distro unless I had to, because it probably will 
become painful.
If it is easy enough to keep support of an old distro then why not?
One optional driver not compiling does not seem a good reason to drop support.
Eventually we will need to but that is not a good enough reason IMHO.

Subject: [Emc-developers] old distros

Hi,

I added the EOL date of the official distros to the wiki:
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?MinimumSoftwareVersions
Notice that only stretch and buster are not near end of life.

Recently there have been 2 PRs with code that doesn’t work on old compilers.
https://github.com/LinuxCNC/linuxcnc/pull/689
https://github.com/LinuxCNC/linuxcnc/pull/714

I don’t understand why we support distros that have been released 8 years
ago.
Making newer stuff work on legacy software is just a waste of developers
time.
If people can’t be bothered to update the distro, why would they be
bothered to update linuxcnc?
As far as Im aware everything works on stretch.

After a short discussion with jepler on irc, he mentioned that it hasn’t
been decided to drop support, and its unclear on how to decide stuff like
this.

My proposal:
Keep 2.8 as it is, as it's near the release.

Drop support for anything earlier than Stretch in master, and as soon as
python3 support is working, drop support for python2 in master.
Python2 is EOL since January, and it's not feasible to support both.

Rene
