1.1. Install Crux 3.4

Installation of minimal Crux 3.4 Gnu\Linux system, with selected packages from core, opt and contrib ports. Process of installation documented can be executed from iso or from existing gnu\linux installation. Read Hand book 3.4, .

If you are booting from crux iso and is not your keyboard layout of choice run;

        # loadkeys dvorak

1.1.1. Download iso

Visit crux download page for more notes before downloading iso. Script setup-iso.sh downloads iso from master repo and checks md5sum.

        $ curl -k -O https://serverop.de/crux/crux-3.4/iso/crux-3.4.iso
        $ curl -k -O https://serverop.de/crux/crux-3.4/iso/crux-3.4.md5
        $ md5sum crux-3.4.iso
        73bf4d301e2dcfb0636cb7fc2a9e8fde crux-3.4.iso

1.1.2. Prepare target

Prepare disk or target location where new system will be installed. Follow steps describe how to create efi and separate partitions such as; bios grub, EFI, boot, root, var, usr, swap and home. For more information about gpt partitions table read devil-detail grub2 on gpt. Script setup-target.sh creates follow partitions;

Create gpt label and set unit size to use;

        (parted) mklabel gpt
        (parted) unit mib

bootloader

Partition used by grub boot loader. Partition size 2M;

        mkpart primary 2 4
        name 1 grub
        set 1 bios_grub on

/boot/efi

EFI System Partition, ESP type EF00. Partition with between 500M and 100M is recommended for standard installations. Partition size 128M;

        (parted) mkpart ESP fat32 4 132
        (parted) name 2 efi
        (parted) set 2 boot on

/boot

Boot partition. Partition with 1G provide room for kernels and bootable iso's that can be directly boot from grub (without root partition). Partition size 1G;

        (parted) mkpart primary ext4 132 1132
        (parted) name 3 boot

/

Core collection installation on root partition uses approximately 2G. Partition with 8G-20G is recommended for a server or desktop with dedicated ports partition or using only compiled packages. Partition size 20G;

        (parted) mkpart primary ext4 1132 21132
        (parted) name 4 root

/var

Var partition is recommended 1G-5G depending on how system is configured. Partition size 2G;

        (parted) mkpart primary ext4 21132 23132
        (parted) name 5 var

Swap (ram)

Swap partition general advice is to have the same size as memory ram, ports system will be configured to build on ram. To build firefox is necessary at least 34G. Partition size 4G;

Is better to create swap partition later using lvm.

        (parted) mkpart primary linux-swap 23132 27132
        (parted) name 6 swap

/home

Home partition on desktop fill the rest of disk space while on server this partition can be unnecessary. Fill the rest of disk space;

Is better to create home partition later using lvm.

        (parted) mkpart primary ext4 27132 100%
        (parted) name 7 home

Create filesystems

        $ sudo mkfs.fat -F 32 /dev/sda2
        $ sudo mkfs.ext4      /dev/sda3
        $ sudo mkfs.ext4      /dev/sda4
        $ sudo mkfs.ext4      /dev/sda5
        $ sudo mkswap	      /dev/sda6
        $ sudo mkfs.ext4      /dev/sda7

1.1.3. Prepare Install

From now on script setup-install.sh create file systems, install packages, configure host metadata and setup ports;

Export target root partition;

	$ export BLK_ROOT=/dev/sda

Export target root directory you want to install;

        $ export CHROOT=/mnt

If you are installing to a directory and not partitions you don't need to mount;

        $ sudo mount $BLK_ROOT $CHROOT

Create follow directories;

        $ sudo mkdir -p $CHROOT/boot
        $ sudo mkdir -p $CHROOT/var
        $ sudo mkdir -p $CHROOT/usr
        $ sudo mkdir -p $CHROOT/media
        $ sudo mkdir -p $CHROOT/home

        $ sudo mkdir -p $CHROOT/dev
        $ sudo mkdir -p $CHROOT/tmp
        $ sudo mkdir -p $CHROOT/proc
        $ sudo mkdir -p $CHROOT/sys

If partition layout is different or target is a directory is not necessary to mount, create only the directories;

        $ sudo mount $BLK_BOOT $CHROOT/boot
        $ sudo mkdir -p $CHROOT/boot/efi
        $ sudo mount $BLK_EFI $CHROOT/boot/efi

        $ sudo mount $BLK_VAR $CHROOT/var
        $ sudo mkdir -p $CHROOT/var/lib/pkg

        $ sudo mount $BLK_HOME $CHROOT/home

Activate Chroot;

        $ sudo mount --bind /dev $CHROOT/dev
        $ sudo mount -vt devpts devpts $CHROOT/dev/pts
        $ sudo mount -vt tmpfs shm $CHROOT/dev/shm
        $ sudo mount -vt proc proc $CHROOT/proc
        $ sudo mount -vt sysfs sysfs $CHROOT/sys

Mount iso or copy packages to target /mnt directory;

        # modprobe isofs
        # modprobe loop
        # mount -o loop crux-3.4.iso $CHROOT/media

1.1.4. Install Crux

Create file $CHROOT/core.lst containing list of binary packages present in $CHROOT/media/crux/core/;

        $ sudo for p in $CHROOT/media/crux/core/*; do echo $p << $CHROOT/core.lst; done

Install temporary pkgadd on $CHROOT;

        $ sudo tar xf /media/crux/core/pkgutils#5.40-1.pkg.tar.xz usr/bin/pkgadd -O > $CHROOT/pkgadd
        $ sudo chmod +x $CHROOT/pkgadd

Edit $CHROOT/core.lst with your preferences, you can remove or add packages from opt collection. Remove lilo if you want grub.

Create package database, it will contain a list of installed packages files.

        $ sudo touch $CHROOT/var/lib/pkg/db

Install all packages listed in $CHROOT/core.lst;

        $ su
        # cd $CHROOT
        while read line; do
                printf "Installing $line;\n"
                $CHROOT/pkgadd -f -r $CHROOT $line
        done < core.lst

1.1.5. Install extra packages

Install additional ports like wireless-tools, grub2 and fakeroot;

        cp $CHROOT/media/crux/opt/* $CHROOT/usr/ports/packages
        cp $CHROOT/media/crux/xorg/* $CHROOT/usr/ports/packages

        # chroot $CHROOT /bin/bash

        pkgadd /usr/ports/packages/fakeroot#*
        pkgadd /usr/ports/packages/dbus#*
        pkgadd /usr/ports/packages/expat#*
        pkgadd /usr/ports/packages/libnl#*
        pkgadd /usr/ports/packages/libpng#*
        pkgadd /usr/ports/packages/freetype#*
        pkgadd /usr/ports/packages/libffi#*
        pkgadd /usr/ports/packages/sqlite3#*
        pkgadd /usr/ports/packages/python#*
        pkgadd /usr/ports/packages/glib#*
        pkgadd /usr/ports/packages/grub2#*
        pkgadd /usr/ports/packages/grub2-efi#*
        pkgadd /usr/ports/packages/wireless-tools#*
        pkgadd /usr/ports/packages/wpa_supplicant#*
        pkgadd /usr/ports/packages/lvm2#*
        pkgadd /usr/ports/packages/mdadm#*
        pkgadd /usr/ports/packages/efivar#*
        pkgadd /usr/ports/packages/efibootmgr#*
        pkgadd /usr/ports/packages/dosfstools#*

        # exit

        $ sudo rm $CHROOT/pkgadd
        $ sudo rm $CHROOT/core.lst

1.1.6. Install extra ports

Create c9 ports;

        $ sudo mkdir $CHROOT/usr/ports/c9-ports

Copy ports from c9-doc/core/ports;

        $ sudo cp -r ports/* $CHROOT/usr/ports/c9-ports/

1.1.7. DNS Resolver

        $ sudo cp /etc/resolv.conf $CHROOT/etc

1.1.8. Install Handbook

        $ sudo cp $CHROOT/media/crux/handbook.txt $CHROOT/home/root/

1.1.9. Basic Skeleton

Copy skeletons from c9-doc/core/conf;

        $ sudo cp -R  conf/skel $CHROOT/etc/
