How to create and where to mount the partition will be +explaind in full detail later on in chapter 4. In my case the LFS +partition is mounted on /mnt/lfs. If I read this book myself and I see +$LFS somewhere, I will pretend that I read /mnt/lfs. If I read that +I have to run this command: cp inittab $LFS/etc I actually will run this: +cp inittab /mnt/lfs/etc +</para> + +<para> +It's important that you do this no matter where you read it; be it in +commands you enter on the prompt, or in a file you edit or create. +</para> + +<para> +If you want, you can set the environment variable LFS. This way you can +literally enter $LFS instead of replacing it by something like +/mnt/lfs. This is accomplished by running: export LFS=/mnt/lfs +</para> + +<para> +If I read cp inittab $LFS/etc, I literally can type cp inittab $LFS/etc +and the shell will replace this command by cp inittab /mnt/lfs/etc +automatically. +</para> + +<para> +Do not forget to set the $LFS variable at all times. If you haven't set +the variable and you use it in a command, $LFS will be ignored and whatever +is left will be executed. The command cp inittab $LFS/etc without the $LFS +variable set, will result in copying the inittab file to the /etc +directory which will overwrite your system's inittab. A file like inittab +isn't that big a problem as it can easily be restored, but if you would +make this mistake during the installation of the C Library, you can +damage things. +</para> + +<para> +One way to make sure that $LFS is set at all times you could add it to +your /root/.bash_profile and/or /root/.bashrc file(s) so everytime you +'su' to user too as to install LFS, the $LFS variable is set for you. +</para> + +</sect1> + |
