+** ISO in loopback mode.
+
+Note: Described method is for using with GRUB2.
+ GRUB2 is installed on target media and archlinux-<YYYY>.<MM>.<DD>-x86_64.iso

+}
+
+
+** ISO in memdisk mode.
+
+Note: Described method is for using with SYSLINUX. Anyway MEMDISK from SYSLINUX can work
+ with other bootloaders.
+ SYSLINUX is installed on target media and archlinux-<YYYY>.<MM>.<DD>-x86_64.iso
+ is at path <TARGET-PATH>.

+
+
+** Network booting (PXE).
+
+All ISOs are ready to act as PXE server, some manual steps are needed
+to setup the desired PXE boot mode.
+Alternatively it is possible to use an existing PXE server following the same logic.
+Note: Setup network first, adjust IP adresses, and respect all slashes "/".
+
+First stage is for loading kernel and initramfs via PXE, two methods described here:
+
+* DHCP + TFTP
+
+Note: All NIC firmwares should support this.
+
+# dnsmasq --port=0 \
+ --enable-tftp \
+ --tftp-root=/run/archiso/bootmnt \
+ --dhcp-range=192.168.0.2,192.168.0.254,86400 \
+ --dhcp-boot=/arch/boot/syslinux/lpxelinux.0 \
+ --dhcp-option-force=209,boot/syslinux/archiso.cfg \
+ --dhcp-option-force=210,/arch/
+
+* DHCP + HTTP
+
+Note: Not all NIC firmware supports HTTP and DNS (if domain name is used).
+ At least this works with iPXE and gPXE.
+
+# dnsmasq --port=0 \
+ --dhcp-range=192.168.0.2,192.168.0.254,86400 \
+ --dhcp-boot=http://192.168.0.7/arch/boot/syslinux/lpxelinux.0 \
+ --dhcp-option-force=209,boot/syslinux/archiso.cfg \
+ --dhcp-option-force=210,http://192.168.0.7/arch/
+
+
+Once the kernel is started from PXE, SquashFS files and other misc files
+inside "arch" directory must be loaded (second stage). One of the following
+methods can be used to serve the rest of live-medium.
+
+* HTTP
+
+# darkhttpd /run/archiso/bootmnt
+
+
+* NFS
+
+# echo "/run/archiso/bootmnt 192.168.0.*(ro,no_subtree_check,no_root_squash)" >> /etc/exports
+# systemctl start nfs-server.service
+
+
+* NBD
+
+Note: Adjust ARCH_201703 as needed.
+
+# cat << EOF > /tmp/nbd-server.conf
+[generic]
+[archiso]
+ readonly = true
+ exportname = /dev/disk/by-label/ARCH_201703
+EOF
+# nbd-server -C /tmp/nbd-server.conf

+
+1) Create one partition entry in MBR and mark it as "active" (booteable).
+Note: Type "b" for FAT32, "83" for EXTFS or "7" for NTFS.
+# fdisk <DEV-TARGET>
+
+2) Create a FAT32, EXTFS or NTFS filesystem on such partition and setup a label.
+Note: COW is not supported on NTFS.

+# mkfs.ext4 -L <FS-LABEL> <DEV-TARGET-N>

+
+4) Extract ISO image on target filesystem.
+# bsdtar -x --exclude=isolinux/ --exclude=EFI/ --exclude=loader/ -f <ISO-SOURCE> -C <MNT-TARGET-N>
+
+5) Install syslinux bootloader on target filesystem.
+# extlinux -i <MNT-TARGET-N>/arch/boot/syslinux
+
+6) Unmount target filesystem.
+# umount <MNT-TARGET-N>

+
+
+* PC-BIOS (ISOHYBRID-MBR):

+Note: This method is the most easily, quick and dirty, but is the most limited
+ if you want to use your target medium for other purposes.

+1) Create one partition entry in GPT (of type "ef00")
+# gdisk <DEV-TARGET>
