Hello! I've noticed something unusual when checking this PR at commit
38368e9780cdccbe451c403488cdb32c9aa09711:

• The page pages.it/linux/lxc-create.md seems to be a copy of pages/linux/lxc-create.md (61% matching).

Is this intended? If so, just ignore this comment. Otherwise, please double-check the commits.
