## Installation of Coreutils

Normally the functionality of `uname` is somewhat broken, in that the `-p` switch always returns "unknown". The following patch fixes this behaviour for Intel architectures:

    patch -Np1 -i ../coreutils-5.0-uname.patch

We do not want Coreutils to install its version of the `hostname` program, because it is inferior to the version provided by Net-tools. Prevent its installation by applying a patch:

    patch -Np1 -i ../coreutils-5.0-hostname-2.patch

Now prepare Coreutils for compilation:

    ./configure --prefix=/usr

Compile the package:

    make

The `su` program from Coreutils wasn't installed in Chapter 5 because it needed root privilege to do so. We're going to need it in a few moments for the test suite. Therefore we work around the problem by installing it now:

    make install-root

This package has a test suite available which can perform a number of checks to ensure it built correctly. However, this particular test suite makes some assumptions that aren't quite valid at this early stage of Chapter 6. We therefore make a few adjustments to allow the tests to run properly. Should you choose not to run the test suite, skip down to "Install the package". The following commands will prepare us for the test suite. Create two dummy groups and a dummy user name:

    echo "dummy1:x:1000" >> /etc/group
    echo "dummy2:x:1001:dummy" >> /etc/group
    echo "dummy:x:1000:1000:::/bin/bash" >> /etc/passwd

Some tests are meant to run as root:

    make check-root

The remainder of the tests are run as the dummy user:

    su dummy -c "make RUN_EXPENSIVE_TESTS=yes check"

Remove the dummy groups and user name:

    sed -i.bak '/dummy/d' /etc/passwd /etc/group

Install the package:

    make install

And move some programs to their proper locations:

    mv /usr/bin/{basename,cat,chgrp,chmod,chown,cp,dd,df} /bin
    mv /usr/bin/{dir,dircolors,du,date,echo,false,head} /bin
    mv /usr/bin/{install,ln,ls,mkdir,mkfifo,mknod,mv,pwd} /bin
    mv /usr/bin/{rm,rmdir,shred,sync,sleep,stty,su,test} /bin
    mv /usr/bin/{touch,true,uname,vdir} /bin
    mv /usr/bin/chroot /usr/sbin

Finally, create a few necessary symlinks:

    ln -s test /bin/[
    ln -s ../../bin/install /usr/bin
