 The command honors `core.filemode` configuration variable.  If
 your repository is on an filesystem whose executable bits are

+unreliable, this should be set to 'false' (see gitlink:git-config[1]).
 This causes the command to ignore differences in file modes recorded
 in the index and the file mode on the filesystem if they differ only on
 executable bit.   On such an unfortunate filesystem, you may
 need to use `git-update-index --chmod=`.
 
+Quite similarly, if `core.symlinks` configuration variable is set
+to 'false' (see gitlink:git-config[1]), symbolic links are checked out

+from symbolic link to regular file.
+
 The command looks at `core.ignorestat` configuration variable.  See
 'Using "assume unchanged" bit' section above.
