[Bug manual/15849] New: References to pt_chown in "running make install" section of manual are outdated.


http://sourceware.org/bugzilla/show_bug.cgi?id=15849

            Bug ID: 15849
           Summary: References to pt_chown in "running make install"
                    section of manual are outdated.
           Product: glibc
           Version: 2.18
            Status: NEW
          Severity: normal
          Priority: P2
         Component: manual
          Assignee: unassigned at sourceware dot org
          Reporter: brooks at gcc dot gnu.org
                CC: mtk.manpages at gmail dot com, roland at gnu dot org

Glibc was recently changed to avoid building and installing pt_chown by
default, and this change was reflected in some sections of the manual.

However, there is a paragraph in the "Running make install" section of the
manual that needs to be updated:
"One auxiliary program, /usr/libexec/pt_chown, is installed setuid root. This
program is invoked by the grantpt function; it sets the permissions on a
pseudoterminal so it can be used by the calling process. This means programs
like xterm and screen do not have to be setuid to get a pty. (There may be
other reasons why they need privileges.) If you are using a Linux kernel with
the devptsfs or devfs filesystems providing pty slaves, you don't need this
program; otherwise you do. The source for pt_chown is in
login/programs/pt_chown.c."
(http://www.gnu.org/software/libc/manual/html_node/Running-make-install.html)

Most of this should be moved to the section on "--enable-pt_chown" entry on the
previous "Configuring and compiling" page, and the remainder should be replaced
with simply a mention that if --enable-pt_chown is set, pt_chown will be
installed and will be setuid root.
