I'm working on some improvements to the Developer Guide. One of those is a section that explains more clearly to people new to Ceph how to know that your submodules are out of date and what to do when they are. The following location (inb4 I know that this is not the optimal place for this information, which is the whole point of this exercise) explains how to update submodules: https://docs.ceph.com/en/latest/install/clone-source/?highlight=update%20sub... Sometimes in my local repo, I get the following messages after I run "$ git reset --hard ceph/master", and I'd like to understand what's going on here, and whether I should expect the submodule-updating procedure to remedy it: zdover@zdover-ThinkPad-T530:~/Documents/ceph/src$ git status On branch master Your branch is up to date with 'remotes/origin/master'. Untracked files: (use "git add <file>..." to include in what will be committed) lua/ nothing added to commit but untracked files present (use "git add" to track) Any insight into this matter is welcome.
