While traversing the directory symbolic links are not followed. Instead

The callback function is only called for items which are on the same

The file owner and group play a role in determining access because the
file has one set of access permission bits for the owner, another set
that applies to users who belong to the file's group, and a third set of
-bits that applies to everyone else. @xref{Access Permission} for the
+bits that applies to everyone else. @xref{Access Permission}, for the
details of how access is decided based on this data.
When a file is created, its owner is set to the effective user ID of the
attributes, contains two kinds of information: the file type code, and
the access permission bits. This section discusses only the access
permission bits, which control who can read or write the file.

The source for @file{pt_chown} is in @file{login/programs/pt_chown.c}.
+After installation you might want to configure the timezone and locale
+installation of your system. The GNU C library comes with a locale
+database which gets configured with @code{localedef}. For example, to
+set up a German locale with name @code{de_DE}, simply issue the command
+@samp{localedef -i de_DE -f ISO-8859-1 de_DE}. To configure all locales
+that are supported by glibc, you can issue from your build directory the
+command @samp{make localedata/install-locales}.
+
+To configure the locally used timezone, you can either set the @code{TZ}
+environment variable. The script @code{tzselect} helps you to select
+the right value. As an example for Germany, tzselect would tell you to
+use @samp{TZ='Europe/Berlin'}. For a system wide installation (the
+given paths are for an installation with @samp{--prefix=/usr}), link the
+timezone file which is in @file{/usr/share/zoneinfo} to the file
+@file{/etc/localtime}. For Germany, you might execute @samp{ln -s
+/usr/share/zoneinfo/Europe/Berlin /etc/localtime}.
