====== Installing PLD Linux based on Rescue CD ======


===== TOC =====
/* UndefinedMacro: TableOfContents(None) */ 

===== Requirements =====
Download RescueCD from : [[docs:rescuecd|Rescue CD]]. PLD rescue new is preferred.


===== Partition disk =====
Use for example ''cfdisk'' to partition your destination disk. Usually root partition (/) and swap is enough.

\\ :!: Write something more here :!: 



===== Filesystem =====
Initiate swap space:
<file># mkswap /dev/sda1
</file>

Make filesystem (ex. ext4): 
<file># mkfs.ext4 /dev/sda2
</file>

We need to create mountpoint and mount partition into it:
<file># mkdir /pld
# mount /dev/sda2 /pld
</file>

If more partitions are going to be used (like you want to have separate /boot or /home) then these need to be mounted now, too.
===== Network configuration of RescueCD =====

RescueCD and installed PLD system will use the same way of configuring network.

By default both try to use DHCP to automatically configure network interface during a boot process.
If that works for you you don't need to do anything.

If manual configuration is required then configure networking using files below.

==== eth0 interface configuration: /etc/sysconfig/interfaces/ifcfg-eth0 ====

Assume you want 192.168.0.2 with /24 network (CIRD notation is preferred)

<file>DEVICE=eth0
IPADDR=192.168.0.2/24
ONBOOT=yes
BOOTPROTO=none
</file>

==== Default gateway and default gateway interface configuration: /etc/sysconfig/network ====

enable networking, ipv4 networking, set default gateway and interface which should be used to reach geteway:

<file>
NETWORKING=yes
IPV4_NETWORKING=yes
GATEWAY=192.168.0.254
GATEWAYDEV=eth0
</file>

==== DNS resolver IP addresses configuration: /etc/resolv.conf ====

Add default nameservers:

<file>nameserver 1.1.1.1
nameserver 8.8.8.8</file>

=== Reload network ===

<file># service network restart</file>


===== Poldek's configuration =====
In file **/etc/poldek/repos.d/pld.conf** We need to set **_arch = ** to chosen architecture ex. 



<file>_arch   = x86_64
</file>


===== Packages installation =====

All packages are installed using **poldek** tool (it is a package manager for PLD).

<file># rpm --root /pld --initdb
# poldek --root /pld

poldek> install LIST OF PACKAGES REQUIRED FOR RUNNING SYSTEM
</file>

Packages which make sense to be installed:

<file>udev pwdutils dhcpcd poldek vim geninitrd grub2 e2fsprogs tzdata glibc-localedb-all</file>

If **xfs** filesystem was chosen then please install:

<file>xfsprogs</file>

===== Kernel installation =====


==== Prepare to install kernel ====

Before installing kernel you need to mount kernel proc, sys and dev filesystems inside of chroot:

<file># mount -o bind /proc /pld/proc
# mount -o bind /sys /pld/sys
# mount -o bind /dev /pld/dev
</file>

You need to tell initrd generator which hardware driver is needed to access your rootfs filesystem
by setting scsi_hostadapter alias in **/etc/modprobe,d/modprobe.conf** (or any other file in that directory)

<file>alias scsi_hostadapter ahci</file>

**lspci -k** command run on rescuecd can help you to find a correct driver:

<file>
00:01.1 IDE interface: Intel Corporation 82371AB/EB/MB PIIX4 IDE (rev 01)
        Kernel driver in use: ata_piix
        Kernel modules: ata_piix, pata_acpi, ata_generic
</file>

Note **Kernel driver in use: ata_piix** (alias scsi_hostadapter ata_piix)

While at it, on actual installed PLD system (not needed on rescuecd), you can do the same for network card driver:

<file>alias netdev-eth0 e1000e</file>

(again **lspci -k** will help to choose correct one)


Configure **/pld/etc/fstab** ex.: 

<file>/dev/sda1 swap swap defaults 0 0
/dev/sda2 /    ext4 defaults 0 0
</file>

\\ :!: Write something more here :!: 



==== Kernel installation ====


<file># poldek --root /pld -i kernel</file>

or

<file>#poldek --root /pld -i kernel-some-specific-version</file>

You can also install multiple different kernels.

By default kernel installation also generates initrd based on mounted /proc, /sys, /dev files and configured fstab, modprobe.conf and few others configuration files. generated initrd (which by default is initramfs cpio image) is saved in /boot.

----

There are two initrd generators used in PLD: geninitrd and dracut. Choose one.

=== geninitrd ===

If something fails or you want to regenerate initrd manually you can do it using:

<file>/sbin/geninitrd -v -f /boot/initd-XXX-Y.gz XXX-Y</file>

command. Real example:

<file>/sbin/geninitrd -v -f /boot/initd-4.20.3-1.gz 4.20.3-1</file>

//-v// option causes geninitrd to write additional information, so you can see if proper kernel modules are being installed into initrd.

=== dracut ===

:!: Write something more here :!:

----

PLD supports systemd and non-systemd installations. In case of systemd installation you need to install package

<file>systemd</file>

package and setup default boot kernel cmdline option in grub/lilo. Add

<file>init=/bin/systemd systemd.unit=graphical.target</file>


If booting with new initrd fails you can use **debuginitrd** and **debuginitrd=sh** boot kernel cmdline options to debug the problem.
===== Bootloader =====

==== grub2 ====

Install grub2 on boot sector of disk:

<file>grub-install /dev/sda</file>

Generate configuration file for grub2:

<file>update-grub</file>

Resulting file is saved as **/boot/grub/grub.cfg**. Setting custom options for grub2 can be done in **/etc/sysconfig/grub** (then regenerate **grub.cfg** with **update-grub** command).


==== lilo (deprecated) ====
Edit **/pld/etc/lilo.conf** 

<file>boot=/dev/sda
read-only
lba32
prompt
timeout=100

image=/boot/vmlinuz
        label=pld
        root=/dev/sda2
        initrd=/boot/initrd
</file>
And execute: 

<file># chroot /pld /sbin/lilo
</file>

==== Advanced configuration ====
Advanced lilo and grub configuration is described here: [[:Docs:man:Bootloader|../Bootloader]] 



===== udev =====
\\ :!: Write something more here :!: 



===== User accounts =====

By default **root** account doesn't have any password set and by default that will prevent you from logging in. Setup root password

<file>chroot /pld && passwd</file>

\\ :!: Write something more here :!: 

===== Finishing =====

If manual network configuration was required for RescueCD then most liikely you need to repeat that [[docs:man:installing_pld_linux_based_on_rescue_cd#network_configuration_of_rescuecd|step]] on installed PLD system, too.

Last step is umount all filesystems:

<file>umount -R /pld</file>

and reboot:

<file>reboot</file>.
