Correct. fakeroot would report that the files that are actually owned by the user who is running fakeroot are owned by root; the cached stat information in the index would be "corrected" to say that they are owned by root. So once the index is refreshed like so, things will become consistent. > The unexpected result is: > > "fakeroot git status" updates the index, and the index now says all files > are owned by uid:0. You should learn to expect it; that is how fakeroot works. > "git diff-index --name-only HEAD" is used to test if the git tree is dirty > without fakeroot, concluding all files have changed, since their owner UID > is changed. The lower-level plumbing diff-* commands are meant to be used by scripts that refresh the index once upfront. If you are using "diff-index" for the "is the tree dirty?" check without running "update-index --refresh", then you are not using the command correctly.
