51Older distributions are not officially supported, which means that it
52may or may not work. It all depends on your luck. It should be possible
53to compile latest LTP even on slightly older distributions than we
54support with a few manual tweaks, e.g. disabling manually tests for
55newly added syscalls, etc. **Trivial fixes/workarounds may be accepted,
56but users are encouraged to move to a newer distro.**
57
58If latest LTP cannot be compiled even with some amount of workarounds,
59you may result to older LTP releases, however these are **not** supported
60in any way. Also if you are trying to run LTP on more than 10 years old
61distribution you may as well reconsider you life choices.
