Arch Linux

引导

https://github.com/thias/glim可以研究下

方法1

需要内存大于1G

mkdir /boot/iso
cd /boot/iso
wget -N -O ipxe.lkrn \
"https://www.archlinux.org/static/netboot/\
ipxe.28ebfe8a66ac.lkrn"
# edit /etc/grub.d/40_custom
menuentry "Network Boot" {
  linux16 /boot/ipxe.lkrn
}
update-grub
reboot
choose netboot
choose mirror
boot arch

方法2

不能加载到内存

wget -N "http://mirror.wdc1.us.leaseweb.net/archlinux/iso/\
2018.02.01/archlinux-2018.02.01-x86_64.iso"
# edit /etc/grub.d/40_custom
menuentry '[loopback]archlinux-2018.02.01-x86_64.iso' {
  set imgdevpath="/dev/disk/by-uuid/af4ac7cd-061d-47c5-85c5-460a2821f2aa"
  set isofile='/boot/iso/archlinux-2018.02.01-x86_64.iso'
  loopback loop $isofile
  linux (loop)/arch/boot/x86_64/vmlinuz img_dev=$imgdevpath img_loop=$isofile earlymodules=loop
  initrd (loop)/arch/boot/x86_64/archiso.img
}

方法3

需要独立的盘

cd /boot
mkdir iso
mkdir syslinux
cd iso
wget -N "http://mirrors.163.com/archlinux/iso/\
2018.02.01/archlinux-2018.02.01-x86_64.iso"
cd ../syslinux
# apt -y install syslinux extlinux
cp /usr/lib/syslinux/modules/bios/*.c32 ./
# extlinux --install /boot/syslinux
# write syslinux
# edit syslinux.cfg
LABEL arch_iso
  LINUX memdisk
  INITRD /boot/iso/archlinux-2018.02.01-x86_64.iso
  APPEND iso
reboot

方法4

mkdir /boot/iso
cd /boot/iso
wget -N "http://mirrors.163.com/archlinux/iso/\
2018.02.01/archlinux-2018.02.01-x86_64.iso"
apt -y install syslinux
cp /usr/lib/syslinux/memdisk /boot/
# edit /etc/grub.d/40_custom
menuentry 'Arch ISO to RAM' {
  set root='(hd0,msdos1)'
  echo 'Loading Memdisk...'
  linux16 /boot/memdisk iso raw
  echo 'Loading ISO...'
  initrd16 '/boot/iso/archlinux-2018.02.01-x86_64.iso'
}
