I have spent quite a lot of time over the years trying to get LTP
working on our embedded systems (uClibc, maybe 32MB of RAM) and it is
possible. We added a few command line options to reduce the memory
usage of tests, although it does involve writing your own test script
with those parameters tweaked.

However it does seem like the project is mostly funded and driven by
enterprise Linux companies so it's a constant battle keeping up to
date. I think we are stuck on a 2 year old version or something like
that and haven't managed to allocate enough resources to get the
recent versions running well.

It probably is something I will pick up again at some point in the
future though. Maybe it's worth suggesting as a CELF project...
