12. Installing the rest of the basic system software

The rest of the software that's part of our basic system will be installed in this section. You don't need all the software, but it's recommended to have it.

12.1 Installing E2fsprogs

Installing E2fsprogs

When compiling I'm getting this error: mke2fs.c:142:SCSI_DISK_MAJOR not defined. I solved it the following way:

Please note that I have no idea what this does when you're using a SCSI system, but I can guess not a heck of a lot of good. Since I'm using an IDE system this doesn't harm me. If you're using SCSI you're on your own I'm afraid since I have no idea on how to fix this. Perhaps you don't even get it when using (a) SCSI disk(s).

Creating the checkroot bootscript

We'll create a checkroot bootscript so that whenever we boot our LFS system, the root file system will be checked by fsck. 

#!/bin/sh
# Begin /etc/init.d/checkroot
 
echo "Activating swap..."
/sbin/swapon -av
 
if [ -f /fastboot ]
then
  echo "Fast boot, no file system check"
else
  mount -n -o remount,ro /
  if [ $? = 0 ]
  then
    if [ -f /forcecheck ]
    then
      force="-f"
    else
      force=""
    fi
 
    echo "Checking root file system..."
    fsck $force -a /
     
    if [ $? -gt 1 ]
    then
      echo
      echo "fsck failed. Please repair your file system manually by"
      echo "running fsck without the -a option"
      
      echo "Please note that the file system is currently mounted in"
      echo "read-only mode."
      echo "
      echo "I will start sulogin now. CTRL+D will reboot your system."
      /sbin/sulogin
      /reboot -f
    fi
  else
    echo "Cannot check root file system because it is not mounted in"
    echo "read-only mode."
  fi
fi
 
# End /etc/init.d/checkroot

Updating /etc/init.d/umountfs

echo "Deactivating swap..."
/sbin/swapoff -av

Creating proper permissions and creating symlink

12.2 Installing File

12.3 Installing Libtool

12.4 Installing Modutils

12.5 Installing Linux86

This package will only be used, as far as I can tell and know, for the installation of Lilo which will be installed next. So you could remove the two programs as86 and ld86 after you've installed Lilo.

Copying kernel image files

12.7 Installing DPKG

We don't install the Debian Package manger itself, but a small program that is shipped with this package; the start-stop-daemon program. This program is very useful in boot scripts so we're going to use it.

12.8 Installing Sysklogd

12.14 Installing Shadow Password

This package contains the utilities to modify user's passwords, add new users/groups, delete users/groups and more. I'm not going to explain to you what 'password shadowing' means. You can read all about that in the doc/HOWTO file. There's one thing you should keep in mind, if you decide to use shadow support, that programs that need to verify passwords (examples are xdm, ftp daemons, pop3d, etc) need to be 'shadow-compliant', eg. they need to be able to work with shadowed passwords.

If you decide you don't want to use shadowed passwords (after you're read the doc/HOWTO document), you still use this archive since the utilities in this archive are also used on system which have shadowed passwords disabled. You can read all about this in the HOWTO. Also note that you can switch between shadow and non-shadow at any point you want.

Now is a very good moment to read section #5 of the doc/HOWTO file. You can read how you can test if shadowing works and if not, how to disable it. If it doesn't work and you haven't tested it, you'll end up with an unusable system after you logout of all your consoles, since you won't be able to login anymore. You can easily fix this by passing the init=/sbin/sulogin parameter to the kernel, unpack the util-linux archive, go to the login-utils directory, build the login program and replace the /bin/login by the one in the util-linux package. Things are never hopelessly messed up, but you can avoid a hassle by testing properly and reading manuals ;)

12.15 Installing GNU C++ Library

The installation by running make install right now will fail because it can't find all the header files that need to be copied to /usr/include/g++-v3. The thing is, the installation script tries to find the files in the src/bits src/shadow src/ext and src/backwards directories. The files are actually in the bits, shadow, ext and backwards directories in the top-level directory. I don't know who to blame; the make program, or the Makefile file. Either way, by making a few symlinks and copying some extra header files to a different directory the installation will finish properly.

To setup up the directories and file in such a way that the Makefile script can find them, execute the following commands from within the src directory: 

ln -s ../bits bits
ln -s ../backward backward
ln -s ../ext ext
ln -s ../shadow shadow
cp ../stl/bits/* bits
cp ../stl/backward/* backward
cp ../stl/ext/* ext

Now that the files are in a place where they can be found during make install, we can proceed with this step.
