Partition
Check if you are in efi mode:
# efivar -l
Then format your disk using parted:
# parted /dev/sda
(parted) mkpart ESP fat32 1M 513M
(parted) set 1 boot on
(parted) mkpart primary ext4 513M 100%
Check if your partition is aligned:
# blockdev --getalignoff /dev/sda
0
I have 2 disks, one for ssd, the other for hdd, so I want to share the swap partition, and locate the /var directory in the hdd, modify it via:
# mkfs.ext4 /dev/sda2
# mkfs.vfat -F32 /dev/sda1
# mount /dev/sda2 /mnt
# mkdir -p /mnt/boot
# mount /dev/sda1 /mnt/boot
# swapon /dev/sdb1
# mkdir /media/
# mount /dev/sdb2 /media
# mkdir /media/var_for_sda
# ln -s /media/var_for_sda /mnt/var
Now you could do pacstrap.
Installation
Installation are the same as the guildeline show,
# pacman -S dosfstools efibootmgr
# bootctl --path=/boot install
# vim /boot/loader/entries/arch.conf
title Arch Linux
linux /vmlinuz-linux
initrd /initramfs-linux.img
options root=/dev/sda2 rw
# vim /boot//loader/loader.conf
#timeout 3
default arch
timeout 5
For wireless connection:
# pacman -S iw wpa_supplicant
# pacman -S dialog
Modification of the /etc/fstab:
# /dev/sda2
UUID=xxxxxxxxxxxxxxxxxxxxxxxx / ext4 default,rw,data=ordered,noatime,discard 0 1
# /dev/sda1
UUID=xxxxxxxxxxxxxxxxx /boot vfat rw,noatime,discard,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro 0 2
# /dev/sdb1
UUID=xxxxxxxxxxxxxxxxxxx none swap defaults 0 0
# /dev/sdb2
UUID=xxxxxxxxxxxxxxxxxxx /media ext4 rw,relatime,data=ordered 0 2
# Only for /var , use mount -o bind
/media/var_for_sda /var none bind
Now reboot everything will be OK.
Configuration For SSD
Profile-sync-daemon for optimization of Browser :
$ yaourt profile-sync-daemon
$ sudo vim /etc/psd.conf
USERS="XXXXX"
BROWSERS="chromium firefox"
USE_OVERLAYFS="yes"
$ sudo systemctl enable psd.service
$ sudo systemctl start psd.service
Test it via:
$ profile-sync-daemon parse
Use firefox -P for changing the profile position. I put all of the profils on HDD.
For chromium, softlink the ~/.config/chromium to HDD disk then you play the tricks for avoiding HDD from too much write. .
Quickly Add User
Use following command for quickly adding the user with specified priviledge:
# useradd -m -g root -G \
audio,video,floppy,network,rfkill,scanner,storage,optical,power,wheel,uucp -s \
/usr/bin/zsh xxxxx
# passwd xxxxx
