In other words, yes, the illustration patch you are responding to assumes that the "reinit" variable is set correctly (i.e. the HEAD exists and sensibly readable if you run "git init" in an already functioning working tree) and we can use it to avoid the filemode check. > Using a new file for the filemode test would be a natural > improvement. That becomes necessary only if we want to futz with core.filemode while doing "reinit", as .git/config can be a symlink. When we are creating a repository from scratch, we always create a regular file to prepare .git/config, and there is no need to do that, if we are happy to set core.filemode the same way as core.symlinks, i.e. only check once when the repository is created. No? Thanks.
