Installing PLD Linux based on Rescue CD

Download RescueCD from : Rescue CD. PLD rescue new is preferred.

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

There are many ways you can partition your disk. Simple example below:

• cfdisk /dev/sdX (assuming fresh disk visible in system as sdX)
• choose GPT partition table
• create 10MB BIOS Boot partition
• create 1GB EFI System partition
• create Linux partition (or more partitions) for PLD

Initiate swap space:

# mkswap /dev/sda1

Make filesystem (ex. ext4):

# mkfs.ext4 /dev/sda2

We need to create mountpoint and mount partition into it:

# mkdir /pld
# mount /dev/sda2 /pld

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.

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.

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

DEVICE=eth0
IPADDR=192.168.0.2/24
ONBOOT=yes
BOOTPROTO=none

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

NETWORKING=yes
IPV4_NETWORKING=yes
GATEWAY=192.168.0.254
GATEWAYDEV=eth0

Add default nameservers:

nameserver 1.1.1.1
nameserver 8.8.8.8

# service network restart

In file /etc/poldek/repos.d/pld.conf We need to set _arch = to chosen architecture ex.

_arch   = x86_64

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

# rpm --root /pld --initdb
# poldek --root /pld

poldek> install LIST OF PACKAGES REQUIRED FOR RUNNING SYSTEM

Packages which make sense to be installed:

udev pwdutils dhcpcd poldek vim geninitrd grub2 e2fsprogs tzdata glibc-localedb-all

If xfs filesystem was chosen then please install:

xfsprogs

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

# mount -o bind /proc /pld/proc
# mount -o bind /sys /pld/sys
# mount -o bind /dev /pld/dev

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)

alias scsi_hostadapter ahci

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

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

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:

alias netdev-eth0 e1000e

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

Configure /pld/etc/fstab ex.:

/dev/sda1 swap swap defaults 0 0
/dev/sda2 /    ext4 defaults 0 0

Write something more here

# poldek --root /pld -i kernel

or

#poldek --root /pld -i kernel-some-specific-version

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.

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

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

command. Real example:

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

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

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

systemd

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

init=/bin/systemd systemd.unit=graphical.target

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

Install grub2 on boot sector of disk:

grub-install /dev/sda

Generate configuration file for grub2:

update-grub

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).

Edit /pld/etc/lilo.conf

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

image=/boot/vmlinuz
        label=pld
        root=/dev/sda2
        initrd=/boot/initrd

And execute:

# chroot /pld /sbin/lilo

Advanced lilo and grub configuration is described here: ../Bootloader

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

chroot /pld && passwd

If manual network configuration was required for RescueCD then most liikely you need to repeat that step on installed PLD system, too.

Last step is umount all filesystems:

umount -R /pld

and reboot:

reboot

.
