+before installing them.  Don't rely on that; compile everything first.
+If you are installing glibc as your primary C library, we recommend you
+shut the system down to single-user mode first, and reboot afterward.
+This minimizes the risk of breaking things when the library changes out
+from underneath.
+
+   If you are upgrading from a previous installation of glibc 2.0 or
+2.1, `make install' will do the entire job.  If you're upgrading from
+Linux libc5 or some other C library, you need to rename the old
+`/usr/include' directory out of the way first, or you will end up with
+a mixture of header files from both libraries, and you won't be able to
+compile anything.  You may also need to reconfigure GCC to work with
+the new library.  The easiest way to do that is to figure out the
+compiler switches to make it work again
+(`-Wl,-dynamic-linker=/lib/ld-linux.so.2' should work on Linux systems)
+and use them to recompile gcc.  You can also edit the specs file
+(`/usr/lib/gcc-lib/TARGET/VERSION/specs'), but that is a bit of a black
+art.
+
+   You can install glibc somewhere other than where you configured it
+to go by setting the `install_root' variable on the command line for
+`make install'.  The value of this variable is prepended to all the
+paths for installation.  This is useful when setting up a chroot
+environment or preparing a binary distribution.
+
+   Glibc 2.1 includes two daemons, `nscd' and `utmpd', which you may or
+may not want to run.  `nscd' caches name service lookups; it can
+dramatically improve performance with NIS+, and may help with DNS as
+well.  `utmpd' allows programs that use the old format for the `utmp'
+file to coexist with new programs.  For more information see the files
+`nscd/README' and `login/README.utmpd'.
+
+   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 2.1 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'.

+
+Specific advice for Linux systems
+=================================
+
+   If you are installing GNU libc on a Linux system, you need to have
+the header files from a development kernel around for reference.  You
+do not need to use the development kernel, just have its headers where
+glibc can get at them.  The easiest way to do this is to unpack a
+development kernel in a directory such as `/usr/src/linux-dev'.  In that
+directory, run `make config' and accept all the defaults.  Then
+configure glibc with the option
+`--with-headers=/usr/src/linux-dev/include'.  Use the latest
+development kernel you can get your hands on.
+
+   An alternate tactic is to unpack the development kernel and run
+`make config' as above.  Then rename or delete `/usr/include', create a
+new `/usr/include', and make the usual symbolic links of
+`/usr/include/linux' and `/usr/include/asm' into the development kernel
+sources.  You can then configure glibc with no special options.  This
+tactic is recommended if you are upgrading from libc5, since you need
+to get rid of the old header files anyway.
+
+   Note that `/usr/include/net' and `/usr/include/scsi' should *not* be
+symlinks into the kernel sources.  GNU libc provides its own versions
+of these files.
+
+   Linux expects some components of the libc installation to be in
+`/lib' and some in `/usr/lib'.  This is handled automatically if you
+configure glibc with `--prefix=/usr'.  If you set some other prefix or
+allow it to default to `/usr/local', then all the components are
+installed there.
+
+   If you are upgrading from libc5, you need to recompile every shared
+library on your system against the new library for the sake of new code,
+but keep the old libraries around for old binaries to use.  This is
+complicated and difficult.  Consult the Glibc2 HOWTO at
+`http://www.imaxx.net/~thrytis/glibc' for details.
+
+   You cannot use `nscd' with 2.0 kernels, due to bugs in the
+kernel-side thread support.  `nscd' happens to hit these bugs
+particularly hard, but you might have problems with any threaded
+program.

+If you are installing glibc as your primary C library, we recommend you
+shut the system down to single-user mode first, and reboot afterward.
+This minimizes the risk of breaking things when the library changes out

+
+If you are upgrading from a previous installation of glibc 2.0 or 2.1,

+compiler switches to make it work again
+(@samp{-Wl,-dynamic-linker=/lib/ld-linux.so.2} should work on Linux
+systems) and use them to recompile gcc.  You can also edit the specs
+file (@file{/usr/lib/gcc-lib/@var{TARGET}/@var{VERSION}/specs}), but
+that is a bit of a black art.
+
+You can install glibc somewhere other than where you configured it to go

+@samp{make install}.  The value of this variable is prepended to all the
+paths for installation.  This is useful when setting up a chroot
+environment or preparing a binary distribution.
+
+Glibc 2.1 includes two daemons, @code{nscd} and @code{utmpd}, which you
+may or may not want to run.  @code{nscd} caches name service lookups; it
+can dramatically improve performance with NIS+, and may help with DNS as
+well.  @code{utmpd} allows programs that use the old format for the
+@file{utmp} file to coexist with new programs.  For more information see
+the files @file{nscd/README} and @file{login/README.utmpd}.
+
+One auxiliary program, @file{/usr/libexec/pt_chown}, is installed setuid
+@code{root}.  This program is invoked by the @code{grantpt} function; it
+sets the permissions on a pseudoterminal so it can be used by the
+calling process.  This means programs like @code{xterm} and
+@code{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 2.1 Linux
+kernel with the @code{devptsfs} or @code{devfs} filesystems providing
+pty slaves, you don't need this program; otherwise you do.  The source

+@appendixsec Specific advice for Linux systems
+@cindex upgrading from libc5
+@cindex kernel header files
+
+If you are installing GNU libc on a Linux system, you need to have the
+header files from a development kernel around for reference.  You do not
+need to use the development kernel, just have its headers where glibc
+can get at them.  The easiest way to do this is to unpack a development
+kernel in a directory such as @file{/usr/src/linux-dev}.  In that
+directory, run @samp{make config} and accept all the defaults.  Then
+configure glibc with the option
+@samp{--with-headers=/usr/src/linux-dev/include}.  Use the latest
+development kernel you can get your hands on.
+
+An alternate tactic is to unpack the development kernel and run
+@samp{make config} as above.  Then rename or delete @file{/usr/include},
+create a new @file{/usr/include}, and make the usual symbolic links of
+@file{/usr/include/linux} and @file{/usr/include/asm} into the
+development kernel sources.  You can then configure glibc with no
+special options.  This tactic is recommended if you are upgrading from
+libc5, since you need to get rid of the old header files anyway.
+
+Note that @file{/usr/include/net} and @file{/usr/include/scsi} should
+@strong{not} be symlinks into the kernel sources.  GNU libc provides its
+own versions of these files.
+
+Linux expects some components of the libc installation to be in
+@file{/lib} and some in @file{/usr/lib}.  This is handled automatically
+if you configure glibc with @samp{--prefix=/usr}.  If you set some other
+prefix or allow it to default to @file{/usr/local}, then all the
+components are installed there.
+
+If you are upgrading from libc5, you need to recompile every shared
+library on your system against the new library for the sake of new code,
+but keep the old libraries around for old binaries to use.  This is
+complicated and difficult.  Consult the Glibc2 HOWTO at
+@url{http://www.imaxx.net/~thrytis/glibc} for details.
+
+You cannot use @code{nscd} with 2.0 kernels, due to bugs in the
+kernel-side thread support.  @code{nscd} happens to hit these bugs
+particularly hard, but you might have problems with any threaded
+program.
