Hi, I think we are playing with words and context here so I will leave it here.
The quote is in a context and says LXD uses LXCs low level api. It does not say 'LXC is a low level api'.
How does one conclude that from the quote and take it out of context without misleading readers? Any one with a remote awareness of LXC will know that's erroneous. Do you still think your comment was accurate?
Have you used LXC, are you familiar with LXC beyond the quote, are you interested in having an informed discussion on LXC and containers? There has be a basis for informed discussion.
