• Separate password for each encrypted container
• Auto mounting home partition with the key file
• Hibernation support
• Mirror list ordered by the fastest to lowest
• Continuous TRIM
• Intel microcode
• Grub multi-boot loader
• systemd system and service manager
• Partition scheme: BIOS/GPT.
• Firewall support

Content

Chapter	Object	Description
1. Base Installation	1_baseInstall.sh	Install base clean system on Unalocated SDA area
1. Base Installation	1_2_firewallSetup.sh	Configures standart base firewall(nftables approach)
2. User Installation	2_userSetup.sh	Configures standart user settings. ZSwap support

---

Prerequisites

• Download the freshet ISO Arch image Arch ISO
• Free up necessary space on SDA

---

Technical details

• To be able to open swap/home containers within booting without prompting of password there are appropriate file keys at /etc/luks-keys is used by the system.
• In additional home container can be encrypted with the encryption_passphrase_home.
• For hibernation support encrypted swap container must be early opened. To reach this goal /etc/luks-keys/swap key file is embedded into initramfs.
• When hibernation is OFF swap partition is mounted as plain encrypted with random UUID each boot.
• To get more about encryption see.

1. Base Installation

1.1 Partition scheme

NAME	FSTYPE	FSVER	MOUNTPOINT
sda
├─sda1
├─sda2	crypto	1
└sda2	ext4	1.0	/boot
└─sda3	LVM2_m	LVM2
├─{volume_group}-cryptroot	crypto	2
└─root	ext4	1.0	/
├─{volume_group}-cryptswap	crypto	2
└─swap	swap	1	[SWAP]
└─{volume_group}-crypthome	crypto	2
└─home	ext4	1.0	/home

1.2 Variables

• continent_city. Is used to set machine zone. See Arch time zone
• country_for_mirror. Is used to set mirror servers. See Arch_mirrors
• encryption_passphrase_root. Is used to set encryption password for the root container.
• encryption_passphrase_boot. Is used to set encryption password for the boot container. The same as encryption_passphrase_root by default.
• encryption_passphrase_home. Is used to set encryption password for the home container. The same as encryption_passphrase_root by default.
• root_password. Is used to set encryption password for the root user. The same as encryption_passphrase_root by default.
• user_name. Defines user name for th new user.
• user_password. Is used to set encryption password for the new user. The same as encryption_passphrase_root by default.
• volume_group. Defines volume group name to store root,swap,home logical volumes. For example: vg0
• part_root_size. Gigabytes reserved for the root partition.
• part_swap_size. Gigabytes reserved for the swap partition.
• host_name. Defines machines host name.
• with_hibernation. Turns ON/OFF special setup in hibernation purpose for.
• with_firewall. Turns ON/OFF firewall setup. See Arch firewall
• disk_type defines physical disk drive where system is going to be installed to. When SDA, TRIM and swappiness configurations take the part. More details about SSD. More details about SWAP
• Gigabytes reserved for the TMPFS. Is OFF, when equal to zero.

1.3 Installation

• Boot into Arch ISO
• Download Install/1_baseInstall.sh via wget https://github.com/lukashonak/arch-linux/master/Install/1_baseInstall.sh
