Add a definition for what overlay means in the context of git, to clarify the recently introduced overlay-mode in git checkout. Helped-by: Elijah Newren <newren@xxxxxxxxx> Helped-by: Junio C Hamano <gitster@xxxxxxxxx> Signed-off-by: Thomas Gummerer <t.gummerer@xxxxxxxxx> --- v3 incorporates Junios suggestions from [*1*], and clarifies that this only applies to checking out from the index or a tree-ish, and clarifies that the files are updated like in the destination directory of 'cp -R'. I thought of making the same clarification for 'rsync --delete' as well, however I think with it being explicitly specified for 'cp -R', readers should be able to deduce that we are talking about the destination directory there as well. *1*: <xmqq5zsnh7my.fsf@xxxxxxxxxxxxxxxxxxxxxxxxx> Documentation/glossary-content.txt | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/Documentation/glossary-content.txt b/Documentation/glossary-content.txt index 023ca95e7c..0f29075551 100644 --- a/Documentation/glossary-content.txt +++ b/Documentation/glossary-content.txt @@ -287,6 +287,15 @@ This commit is referred to as a "merge commit", or sometimes just a origin/name-of-upstream-branch, which you can see using `git branch -r`. +[[def_overlay]]overlay:: + Only update and add files to the working directory, but don't + delete them, similar to how 'cp -R' would update the contents + in the destination directory.
