    Wink Burn Linux From Scratch to Hard Drive via LiveCD. Need Instructions


    Hi,

    I am having trouble understanding some of the concepts relative to using the Linux from Scratch LiveCd as a stable OS system to make it possible to easily install Linux From Scratch to the hard drive. The thing is that I was told by a Linux specialist that it was not possible to actually burn files from the LiveCD to the hard drive. I am, of course, able to create partitions on the hard drive, I just don't know how or what exactly I'm suppose to do to burn an instance of the LinuxFromScratch LiveCD to my hard drive. I've even noticed that the LinuxFromScratch LiveCD does not have a /boot directory which holds the kernel, so I'm wondering how this will work, in any event.

    If you are experienced in this and can help. Please respond.

    Hello and Welcome.
    I have not tried installing LFS yet but it's my understanding that it's a lot like Gentoo Linux, which I do use, I don't think your friend meant to use the LiveCD to copy from, I think he meant that you only use it to boot your machine and from there you will need to follow the LFS guide to the end. You'll need to get networking setup rather quickly so that you can download the packages that you need to install. In short, it's a source based distro which means that you have to compile everything from source code to run on your machine. It could take a couple of days to get it all installed and that depends on how many packages you install. From the LFS website:
    A LiveCD is a CD that is able to boot your system into a 'live', working operating system, independent of anything on your hard drive. It's a little different than an installation CD, which boots your system into a program that will guide you through the installation of some system onto your hard drive. With a LiveCD, you have an entire system contained on the CD and with that, the freedom to do nearly anything that a system installed on your hard drive can.

    The LFS LiveCD is geared specifically toward providing a reliable host system for the purpose of building Linux From Scratch. Therefore, it may not be what you would envision as a "perfect" Linux system. It should, however, provide you with a comfortable enough environment so that you can, in turn, build your own "perfect" system.

    For a more detailed description of the current version of the LiveCD read the documentation.
    LFS LiveCD was only made to check things out and/or as host for building LFS on your machine and as a Rescue CD.
    Once you get your partitions setup the way it needs to be, then you download and compile LFS piece by piece until you have a working install. I hope this helps a little bit.

    Thanks for responding.

    The problem is this. The LinuxFromScratch LiveCD was meant to be the Host operating system necessary to building the LinuxFromScratch base distro. I was under the impression that a user was to be able to somehow copy necessary files to the hard drive on the computer they wish to have LFS installed to.

    The thing is that, when the developers of LFS created a LiveCD to to make building LFS easier, they forgot to write a manual on how to actually accomplish installing it to hard drive from the LiveCD itself. One must actually be intuitive to figure out what is going on or better yet able to conceive of what is not explicitly stated in regards to how to go about installing the LFS to hard drive from LiveCD. From what I've gathered, a person would basically have to set up network connections to download an iso image of LFS in addition to the LFS-LiveCD to make this possible. With that being said, everything else from that point would make sense. However, from my understanding, it was thought that the LFS-LiveCD could be burned to hard drive like any typical Linux distro being installed but I guess this is not the case with LinuxFromScratch (LFS). This makes things tougher for the programmer (if the LiveCD version of LFS can't be burn to hard drive via the LiveCD itself).

    I was hoping that there would be a more user-friendly way of doing this. And if there is, I haven't figured it out yet. Then again, I am still in the learning process, and undoubtly have learned so much about OS programming because of LFS.

    If anyone can make my life more easier, give me a reply. And to the gentle-person who responded to my post so far, thank you

    Keep reading the manuals. LFS is not for the faint-hearted, but you will learn as much (more) about Linux as a MSCE would learn about Windows servers after spending $10,000 in training. Keep at it. The LiveCD is there NOT to install the OS, but to provide a platform to build the OS which you will install at some point in the process. After the basic OS is bootable from your hard drive, you will continue to build the system until it fits your needs. Read, re-read, and read again. There is a LOT to learn, and master! Remember that you are not just selecting some simple options from a menu, but are making fundamental decisions about the system you are building!
    Sometimes, real fast is almost as good as real time.

    I've finally figured out to accomplish this. I have to modify the bashrc and bash_profile files on the LFS LiveCD. This is just one of the many steps. I will post more once I give it a try.
