+*** Transfer ISO image to target medium (configs/releng)
+
+ISO images names consist of: parabola-<YYYY>.<MM>.<DD>-<TYPE>-<ARCH>.iso
+
+Where:
+ <YYYY> Year
+ <MM> Month
+ <DD> Day
+ <TYPE> netinstall | core
+ <ARCH> i686 | x86_64 | dual(*)
+
+(*) "dual" includes both i686 and x86_64 architectures.
+
+
+** To -> CD / DVD / BD
+
+Note: All ISO images are booteable on a PC-BIOS via "El Torito" in no-emulation mode,
+ All x86_64 ISO images are booteable on a PC-EFI via "El Torito" in no-emulation mode.
+
+Nomeclature:
+ <B> scsibus number
+ <T> target number
+ <L> lun number
+ (Note: see cdrecord -scanbus, for these numbers)
+
+
+1) Write it directly using your favorite recording program.
+# cdrecord dev=<B>,<T>,<L> -dao parabola-<YYYY>.<MM>.<DD>-<TYPE>-<ARCH>.iso
+
+
+** To -> USB Flash Drive (USB-key) / Memory card (SD) /
+ Hard-Disk Drive (HDD) / Solid-State Drive (SSD)
+
+Note: These steps are the general workflow, you can skip some of them,
+ using another filesystem if your bootloader supports it,
+ installing to another directory than "arch/" or using more than
+ one partition. Just ensure that main boot params options
+ (archisolabel= and archisobasedir=) are set correctly according to your setup.
+
+Nomeclature:
+<DEV-TARGET>: Device node of the drive where ISO contents should be copied
+ (example: /dev/sdx)
+<DEV-TARGET-N>: Device node of the partition on <DEV-TARGET>
+ (example: /dev/sdx1)
+<MNT-TARGET-N>: Mount point path where <DEV-TARGET-N> is mounted
+ (example: /mnt/sdx/1)
+<ISO-SOURCE>: Path to the ISO file parabola-<YYYY>.<MM>.<DD>-<TYPE>-<ARCH>.iso
+ (example: ~/parabola-2012.04.16-netinstall-x86_64.iso)
+<FS-LABEL>: Represents the filesystem label of the <ISO-SOURCE>
+ (example: LIBRE_201204 [for all ~/parabola-2012.04.*.iso])
+
+
+* PC-BIOS (MBR):
+
+Note: Using here a MBR partition mode as example, but GPT should also works
+ if machine firmware is not broken.
+ Just ensure that partition is set with attribute "2: legacy BIOS bootable"
+ and use gptmbr.bin instead of mbr.bin for syslinux.
+
+1) Create one partition entry in MBR (of type "b" for FAT32 or "83" for EXTFS)
+ and mark it as "active" (bootable).
+# fdisk <DEV-TARGET>
+
+2) Create a FAT32 or EXTFS filesystem on such partition and setup a label.
+# mkfs.vfat -F 32 -n <FS-LABEL> <DEV-TARGET-N>
+# mkfs.ext4 -L <FS-LABEL> <DEV-TARGET-N>
+
+3) Mount target filesystem.
+# mount <DEV-TARGET-N> <MNT-TARGET-N>
+
+4) Extract ISO image on target filesystem.
+# bsdtar -x --exclude=isolinux/ --exclude=EFI/ -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>
+
+7) Install syslinux MBR boot code on target drive.
+# dd bs=440 count=1 conv=notrunc if=/usr/lib/syslinux/mbr.bin of=<DEV-TARGET>
+
+
+* 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) Dump ISO file to target medium.
+# dd if=<ISO-SOURCE> of=<DEV-TARGET>
+
+
+* PC-EFI (GPT) [x86_64 only]
+
+Note: Using here a GPT partition mode as example, but MBR should also works
+ if machine firmware is not broken.
+
+1) Create one partition entry in GPT (of type "ef00")
+# gdisk <DEV-TARGET>
+
+2) Create a FAT32 filesystem on such partition and setup a label.
+# mkfs.vfat -F 32 -n <FS-LABEL> <DEV-TARGET-N>
+
+3) Mount target filesystem.
+# mount <DEV-TARGET-N> <MNT-TARGET-N>
+
+4) Extract ISO image on target filesystem.
+# bsdtar -x --exclude=isolinux/ --exclude=arch/boot/syslinux/ -f <ISO-SOURCE> -C <MNT-TARGET-N>
+
+5) Extract efiboot.img on EFI/ on target filesystem.
+# mcopy -s -i <MNT-TARGET-N>/EFI/archiso/efiboot.img ::/EFI <MNT-TARGET-N>/
+
+6) Remove uneeded efiboot.img
+# rm <MNT-TARGET-N>/EFI/archiso/efiboot.img
+
+7) Unmount target filesystem.
+# umount <MNT-TARGET-N>
+
+
+
+*** Alternative boot methods (configs/releng)
+
+** ISO in loopback mode.
+
+Note: Described method is for using with GRUB2.
+ GRUB2 is installed on target media and parabola-<YYYY>.<MM>.<DD>-<TYPE>-<ARCH>.iso
+ is at path <TARGET-PATH> on disk <D> and partition <P>,
+ where filesystem is labeled as <TARGET-FS-LABEL>.
+
+menuentry "Parabola GNU/Linux-libre (x86_64)" {
+ set isofile="/<TARGET-PATH>/parabola-<YYYY>.<MM>.<DD>-<TYPE>-<ARCH>.iso"
+ loopback loop (hd<D>,<P>)$isofile
+ linux (loop)/arch/boot/x86_64/vmlinuz archisolabel=<FS-LABEL> img_label=<TARGET-FS-LABEL> img_loop=$isofile
+ initrd (loop)/arch/boot/x86_64/libreiso.img
+}
+
+menuentry "Parabola GNU/Linux-libre (i686)" {
+ set isofile="/<TARGET-PATH>/parabola-<YYYY>.<MM>.<DD>-<TYPE>-<ARCH>.iso"
+ loopback loop (hd<D>,<P>)$isofile
+ linux (loop)/arch/boot/i686/vmlinuz archisolabel=<FS-LABEL> img_label=<TARGET-FS-LABEL> img_loop=$isofile
+ initrd (loop)/arch/boot/i686/libreiso.img
+}
+
+
+** 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 parabola-<YYYY>.<MM>.<DD>-<TYPE>-<ARCH>.iso
+ is at path <TARGET-PATH>.
+ On 32-bit systems, is needed to pass vmalloc=nnM to the kernel, where nn is the size
+ of the ISO image plus 64 MiB (or 128 MiB).
+
+
+LABEL parabola_x64

+ INITRD /<TARGET-PATH>/parabola-<YYYY>.<MM>.<DD>-<TYPE>-<ARCH>.iso

+LABEL parabola_x32
+ LINUX memdisk
+ INITRD /<TARGET-PATH>/parabola-<YYYY>.<MM>.<DD>-<TYPE>-<ARCH>.iso
+ APPEND iso
+
+
+** 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/gpxelinux.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/gpxelinux.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
+# rc.d start rpcbind nfs-common nfs-server
+
+
+* NBD
+
+Note: Adjust LIBRE_201204 as needed.
+
+# cat << EOF > /tmp/nbd-server.conf
+[generic]
+[archiso]
+ readonly = true
+ exportname = /dev/disk/by-label/LIBRE_201204
+EOF
+# nbd-server -C /tmp/nbd-server.conf
