=== What is ExtLinux? ===
+
<noinclude>
 
+
This is the "Ebuild" template.
ExtLinux is a simple and modern systemloader bundled with the syslinux tools. Installation is simple and fast, and thanks to our CoreTeam member Slashbeast the configuration is easily automated.
+
It should be called in the following format:
 
+
<pre>
= Installing ExtLinux for funtoo =
+
{{Ebuild
 
+
|Summary=
Installing ExtLinux for funtoo is known to work and supported too. If you like to try it just emerge syslinux
+
|CatPkg=
 
+
|Maintainer=
<console>
+
|Homepage=
# ##i##emerge syslinux
+
</console>
+
 
+
with that you have the complete syslinux tools installed. Another helpful tool you should merge with syslinux is slashbeast's lazykernel tool, so let us merge it too:
+
 
+
<console>
+
# ##i##emerge lazykernel
+
</console>
+
 
+
== Installing extlinux ==
+
 
+
to install extlinux just follow these steps:
+
 
+
<console>
+
# ##i##install -d /boot/extlinux
+
# ##i##extlinux --install /boot/extlinux
+
</console>
+
 
+
The next steps are different depending on if you use an MBR or GPT setup and the HDD you installed on and want to boot from. Let us assume that <tt>/dev/sda</tt> is the drive you will be booting from.
+
 
+
=== MBR ===
+
 
+
If you set up your disk with a MBR partition scheme, run the following:
+
 
+
<console>
+
# ##i##dd bs=440 conv=notrunc count=1 if=/usr/share/syslinux/mbr.bin of=/dev/sda
+
# ##i##cp /usr/share/syslinux/menu.c32 /boot/extlinux/
+
# ##i##cp /usr/share/syslinux/libutil.c32 /boot/extlinux/
+
# ##i##touch /boot/extlinux/extlinux.conf
+
</console>
+
 
+
=== GPT ===
+
 
+
On the other hand, if you formatted your disk using GPT, run these commands:
+
 
+
<console>
+
# ##i##sgdisk /dev/sda --attributes=1:set:2
+
# ##i##sgdisk /dev/sda --attributes=1:show
+
1:2:1 (legacy BIOS bootable)
+
# ##i##dd bs=440 conv=notrunc count=1 if=/usr/share/syslinux/gptmbr.bin of=/dev/sda
+
# ##i##cp /usr/share/syslinux/menu.c32 /boot/extlinux/
+
# ##i##cp /usr/share/syslinux/libutil.c32 /boot/extlinux/
+
# ##i##touch /boot/extlinux/extlinux.conf
+
</console>
+
 
+
== Setting up the Kernel ==
+
 
+
Now if you followed our advice to install lazykernel we have a pretty nice way to solve all the setup with a bit of prework and finish it then. If not you should go to the manual part. :)
+
 
+
=== lazykernel way ===
+
 
+
Edit <tt>/etc/lazykernel.conf</tt>:
+
 
+
{{file|name=/etc/lazykernel.conf|desc= |body=

# Number of the kernels to keep so `lazykernel clean` will not propose to remove them. Default: 3
+
keep_kernels=5
+
 
+
# Sort kernels by 'version' (biggest version first) or by 'mtime' (latest images first). Default: mtime
+
# Sorting by version may fail and 3.3.0-rc2 will be marked as newer than 3.3.0.
+
#sort_by='version'
+
sort_by=mtime

+
# The name for menu entry.
+
menu_entry_name="Funtoo Linux"

+
# Specify what initramfs image to use, if any. (Optional)
+
initramfs='initramfs.cpio.gz'
+
 
+
# Append kernel params, usualy you use it to specify rootfs device, but you can use it to pass switches to initramfs as well.
+
kernel_params="rootfstype=ext4 luks enc_root=/dev/sdb3 lvm root=/dev/mapper/vg-root uswsusp resume=/dev/mapper/vg-swap"

This will generate the modules for you. Copy your kernel form <tt>/usr/src/linux</tt> to <tt>/boot</tt> and generate the <tt>/boot/extlinux/extlinux.conf</tt>. The manual kernel will be the only one supported by lazykernel.

For other kernels, like those created by genkernel or by the binary USE-flag you need to edit your config by yourself. Just open <tt>/boot/extlinux/extlinux.conf</tt> in your favorite editor:
