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 system, for bios_boot systems is only needed the boot partition in the beginning of the disk and can use ext4 file system for example. For more information about gpt partitions table read devil-detail grub2 on gpt. Script setup-target.sh help to create partitions scripts.

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
        

/

There are different ways to achieve disk encryption, the method described uses cryptosetup to create cryptodevice with lvm inside containing root and other partitions such as; var, usr, swap and home.

        (parted) mkpart primary 1132 100%
        (parted) set 4 lvm on
        

Create encrypted block for lvm;

        # modprobe dm-crypt
        # cryptsetup luksFormat /dev/sda4
        # cryptsetup luksOpen /dev/sda4 cryptlvm
        

Create physical group and volume group;

        # pvcreate /dev/mapper/cryptlvm
        # vgcreate vg_system /dev/mapper/cryptlvm
        

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;

        # lvcreate -L 20G -n lv_root vg_system
        

/var

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

        # lvcreate -L 2G -n lv_var vg_system
        

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;

        # lvcreate -L 4G -n lv_swap vg_system
        

/home

On desktop fill the rest of disk space while on server this partition can be replaced with /srv. Fill the rest of disk space;

        # lvcreate -L 120G -n lv_home vg_system
        

Create filesystems

        $ sudo mkfs.fat -F 32 /dev/sda2
        $ sudo mkfs.ext4      /dev/sda3
        $ sudo mkfs.ext4      /dev/vg_system/lv_root
        $ sudo mkfs.ext4      /dev/vg_system/lv_var
        $ sudo mkswap	      /dev/vg_system/lv_swap
        $ sudo mkfs.ext4      /dev/vg_system/lv_home
        

1.1.3. Prepare Install

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

Export target root partition;

        $ export BLK_ROOT=/dev/vg_system/lv_root
        

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/libtirpc#*
        pkgadd /usr/ports/packages/git#*
        pkgadd /usr/ports/packages/tmux#*
        pkgadd /usr/ports/packages/prt-utils#*
        pkgadd /usr/ports/packages/elfutils#*
        
        # exit
        
        $ sudo rm $CHROOT/pkgadd
        $ sudo rm $CHROOT/core.lst
        

1.1.6. Install extra ports
