| == What is ExtLinux? ==
| | This page lists processor instruction sets that can be enabled on Funtoo Linux systems using the {{c|CPU_FLAGS_*}} variables. |
|
| |
|
| 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.

| == 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= | |
| # After configuring, hash or remove line below.
| |
| #CONFIGUREFIRST
| |
| | |
| # 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"
| |
| }}
| |
| | |
| {{fancynote| Please make sure to comment out or delete the second line of the config file...else it will spit out an error.}} | |
| | |
| Now let us setup our kernel with lazykernel. If you have a manual kernel just run:
| |
| | |
| <console> | |
| # ##i##cd <kernel build dir>
| |
| # ##i##lazykernel auto
| |
| </console> | |
| | |
| 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.
| |
| | |
| === manual extlinux.conf ===
| |
| | |
| 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:
| |
| | |
| {{file|name=/boot/extlinux/extlinux.conf|desc= |body= | |
| TIMEOUT 30
| |
| UI menu.c32
| |
| | |
| MENU TITLE Boot Menu
| |
| MENU COLOR title 1;37;40
| |
| MENU COLOR border 30;40
| |
| MENU COLOR unsel 37;40
| |
| | |
| LABEL funtoo1
| |
| MENU LABEL Funtoo Linux KERNEL-VERSION
| |
| LINUX /<kernel>
| |
| INITRD /<initramfs>
| |
| APPEND rootfstype=ext4 luks enc_root=/dev/sdb3 lvm root=/dev/mapper/vg-root uswsusp resume=/dev/mapper/vg-swap
| |
| }} | |
| | |
| That's all. You are now ready for boot. You can also define several LABELs in that list to have multiple kernel selections to choose from before booting.
