BrynNobbs:

== VirtualBox Step By Step Guide ==

Head over to http://www.virtualbox.org and download the latest version for your operating system.

Once you have installed Virtualbox, you will need a Linux distribution to build your LFScript on top of. I recommend heading over to lfscript.org and downloading the latest “From Script” OS. Place the ISO somewhere easy to find.

== Setting Up ==
Now we need to setup Virtualbox.

Start by clicking New in the top left corner. On the next window, just click next. Now its time to name you Virtual PC. Call it whatever you like, then select Linux from the Operating System box and Linux 2.6 in the Version box. Click Next.

== Memory ==

On to memory, I recommend giving at least 1GB of memory to the Virtual PC. So that's at least 1024MB, more if you have it, then click Next.

== Processors ==

While you are in the settings window, click system in the left column. now in the right pane click Processor. You can now move that slider along to match the number or cores your processor has. I set mine to 4 as I use an Intel Core i3, This is a dual core processor with hyperthreading, so 2 real cores, 2 virtual cores. If you have a dual core or more processor, changing this will make a huge difference in the time it takes to compile LFScript scripts.

== Storage ==

Virtual Hard Disk. Leave the settings on this page just as they are and click Next. In the new window that popped up leave everything as is is again and click Next. To save some space, leave the next window set to Dynamic and click Next. We will now decide on what size of disk you want. I usually go for about 20GB to be on the safe side. Once you have decided click Next, followed by Create and finally Create again.

We now have a Virtual PC that can't do anything. We need to add the ISO image we downloaded earlier.

== 'From Script' ==
Click Settings on the main window, and select Storage from the list on the left. You will now see an icon that looks like a CD with the word Empty next to it, click that.

[[File:cd.png]]

Now on the right of the window you will again see a very similar icon with an arrow pointing down, click that one this time. From the list that pop's up click “Choose a Virtual CD/DVD disk file”. Now find the ISO file you downloaded earlier.

We now have a fully working Virtual PC. All you need to do now is click Start in the top corner and watch LFScript Boot from the Live CD.

== Next Steps ==

Now would be a good time to head over to the [[Quick_Start]] page

Installing your system

2012-01-31T20:35:47Z

BrynNobbs: /* Installing a boot loader */

This page will explain how to install a system using LFScript. However, it is also possible to [[Installing your system from a Live CD|install your system from a Live CD]] you built.

== Some notes before you begin ==
It is assumed you already have compiled your system; LFScript is set up on a writeable partition and the <code>packages</code> directory is populated. It is possible you have transferred your packages directory from another machine.

If the hard disk is not yet partitioned, see the [[Quick Start]] page for information on how to do that.

All commands presented here should be executed by the root user. It is assumed that you already have established (writable) access to the LFScript folder.

If you intend to overwrite an existing boot loader, it is recommended you add the <code>os-prober</code> script to your extra packages. If you want <code>os-prober</code> to detect your existing Windows installations, your host system's kernel must have FAT and/or NTFS support.

== Format your partitions ==
If you have partitioned your system as explained on the [[Quick Start]] page, you should have two partitions reserved for your new system: '''sda1''' and '''sda2'''. You might also have set up a third ('''sda3''') for SWAP space. And LFScript is installed on '''sda4'''.

The '''sda2''' partition is optional, but in this example we shall use it to mount the <code>/usr</code> hierarchy of your new system.

<pre>mkfs.ext4 /dev/sda1
mkfs.ext4 /dev/sda2 # Optional</pre>

These commands will install an <code>ext4</code> file system on your partitions. You can use any Linux file system you want, but make sure you have [[Kernel configuration|configured your kernel]] to support it.

If you have not yet configured your swap space, do it now:

<pre>mkswap /dev/sda3</pre>

== Mount your partitions ==
Mount the partition where your are going to install the system:

<pre>mkdir /mnt/install_root
mount /dev/sda1 /mnt/install_root</pre>

If you have set up '''sda2''', then mount it as well:

<pre>mkdir /mnt/install_root/usr
mount /dev/sda2 /mnt/install_root/usr</pre>

You can also change <code>usr</code> to <code>home</code> in the previous commands if you want to have your home directory on the second partition in stead.

== Edit 'install.conf' (optional) ==
LFScript is going to configure your system based on the contents of a file called <code>install.conf</code>. Edit that file if you like.

By default, the file is empty, in which case LFScript will use either default values or ask you for input to configure certain aspects of your system.

<pre>nano scripts/install.conf # or use any other text editor</pre>

== Install your system ==
To actually install the system, run LFScript like you would normally do to build a system and add <code>-i /mnt/install_root</code>. If you want to automatically add an existing OS to the boot menu, be sure to also install <code>os-prober</code>.

<pre>./lfscript <options> -i /mnt/install_root</pre>

For. example:

<pre>./lfscript -Bux "wget nano os-prober" -i /mnt/install_root</pre>

If the target partition only has just enough space to hold the OS that you have built, you might want to add the [[LFScript Switches|-I switch]] to lfscript and specify a directory which has enough space to temporarily store the source code and tool chain.

For example:

<pre>mkdir install_overhead
./lfscript -Bux "wget nano os-prober" -i /mnt/install_root -I install_overhead
rm -rf install_overhead</pre>

== Create /etc/fstab ==
Because partition configurations are unique to your preferences, LFScript can not make the system bootable for you. There are two things you have to configure before the system is able to boot.

First, create the '/etc/fstab' file (based on LFS-SVN20120130):

<pre>cat > /mnt/install_root/etc/fstab << "EOF"
# Begin /etc/fstab

# file system mount-point type options dump fsck
# order
/dev/sda1 / ext4 defaults 1 1
/dev/sda2 /usr ext4 defaults 1 1
/dev/sda3 swap swap pri=1 0 0

proc /proc proc nosuid,noexec,nodev 0 0
sysfs /sys sysfs nosuid,noexec,nodev 0 0
devpts /dev/pts devpts gid=4,mode=620 0 0
tmpfs /run tmpfs defaults 0 0
devtmpfs /dev devtmpfs mode=0755,nosuid 0 0

# End /etc/fstab
EOF</pre>

Be sure to change the first three entries so that they correspond with your set up.

== Installing a boot loader ==
The second thing to do to be able to boot your system, is configuring a boot loader. This is a potentially dangerous thing to do to a system which already has an OS installed, as it could render your existing OS unbootable. You should search the web for instructions on how to recover the bootloader of your existing OS, prior to executing the following commands.

If you already have a Linux OS installed on the system, it may even be better to let it set up the bootloader for you. However, you will need to find out how to do this on your own.

To let your own system configure the boot loader, execute the following commands:

<pre>mount --bind /sys /mnt/install_root/sys # Only required for 'os-prober'
mount --bind /proc /mnt/install_root/proc # Only required for 'os-prober'
mount --bind /dev /mnt/install_root/dev

chroot /mnt/install_root grub-install /dev/sda
chroot /mnt/install_root grub-mkconfig -o /boot/grub/grub.cfg

umount /mnt/install_root/sys # If mounted...
umount /mnt/install_root/proc # If mounted...
umount /mnt/install_root/dev</pre>

== Cleaning up ==
You can now unmount your system:

<pre>umount /mnt/install_root
rm -rf /mnt/install_root</pre>

Reboot your system, and enjoy your new OS:

<pre>shutdown -r now</pre>

== If your system will not boot... ==

<pre>Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block</pre>

This message is caused by the kernel not having been [[Kernel configuration|configured]] properly. You forgot to include support for your hard drive or file system. Remember that in order to boot, these drivers should '''not''' be compiled as a module.

Linux From Script (or 'LFScript') version 4 is an unofficial alternative for 'Automated Linux From Scratch'. LFScript includes thoroughly tested scripts generated from the LFS and BLFS books, which can easily be edited to modify the installation of any package (if you would want to).

When you are satisfied with the scripts, running LFScript will create for each of the selected applications a simple package archive. All archives combined make up your new GNU/Linux operating system. You can instruct LFScript to install the OS on your computer or you can save them to (for example) a USB drive to install them on another computer. LFScript also includes scripts which will combine all your packages and create a Live CD/DVD from them.

If it all went wrong

2012-01-31T00:23:22Z

BrynNobbs:

== If it all went wrong ==

This page will help show you what to do if the build process didn't go well. If you got an error during the build process, try to follow the below instructions. If for some reason you lost power or your computer crashed during the compiling process you should follow the instructions in the [[Aborting and Resuming]] page.

== I got an error before I even started ==

Most of the time, these types of errors are caused by either insufficient privileges or missing dependencies. The easiest way around these errors is to ensure you are running lfscript as the root user and to ensure you are in a publicly writeable folder. You should also check the Linux From Scratch page to make sure you have all of the dependencies installed before you get started.

Alternatively ensure you are running the 'From Script' Live disk as this has all of the required software to run LFScript.

== I get a red error whilst compiling ==

This could be caused by a missing dependency or something is wrong with the script for the package you are trying to install. The first thing you should do is look at the error message, Marcel has spent a lot of time ensuring error messages are understandable. If the message on the screen says it cant download a file, its possible the server is down. You can always get the source package yourself and place it in the sources folder, just ensure you have the exact version LFScript is looking for otherwise you will get an error.

== What else could it be? ==

It could be lots of things unfortunately. But LFScript has a very good log file system. have a look in the log folder. you will find folders with the date and time the build was stated, pick the newest one. Now you just need to locate the log file for the package that failed and see what the error is.

== It still isn't working ==

Well it could be a bug. Report bugs to the [https://bugs.launchpad.net/lfscript/+bugs[bug tracker]]. You can also ask questions [https://answers.launchpad.net/lfscript/[here]].

Lastly remember its only a Virtual PC, you can always just delete it and start again.
