I'm not sure that this is a good suggestion. I would write something as: Older distributions are not officially supported, which means that it may or may not work. It all depends on your luck. It should be possible to compile latest LTP even on slightly older distributions than we support with a few manual tweaks, e.g. disabling manually tests for newly added syscalls manually, etc. If latest LTP cannot be compiled even with some amount of workarounds, you may result to older LTP releases, however these are _not_ supported in any way.

Should we also give some hint about accepting patches/wokrarounds for very old distros?

I'd add it at the end of first paragraph. Or anyone feel free to express it differently. Kind regards, Petr

Debian moves to another release after current testing gets released. We might want to use names (e.g. stretch) instead of "oldstable", "stable".

Hi Petr, LGTM(with fixing as the above suggestions). Thanks for starting this doc.
