This is a reworks of my previous RFC but with changes proposed by Thomas (plus other changes).

Boot as:
* (isolinux) cdrom and cdrom-hibrid-disk: OK
* (pxelinux) TFTP and HTTP: OK
* (extlinux) /arch and /pepe: OK
* (syslinux) /arch and /coco: OK, but see note (@)

(@) Due bug in mmove (from mtools), ldlinux.sys install fails:
(install also fails with real devices like /dev/sdX, unrelated to loop)
# syslinux -i -d /mnt/loop/arch/boot/syslinux /dev/loop1p1
s:/mnt/loop/arch/boot/syslinux/ldlinux.sys: no match for target
syslinux: warning: unable to move ldlinux.sys

* Workaround (always want to read syslinux.cfg on /syslinux even if moving ld-linux.sys to /arch/boot/syslinux)
# mkdir /mnt/loop/syslinux
# mv /mnt/loop/ldlinux.sys /mnt/loop/syslinux
# cp /mnt/loop/isolinux/isolinux.cfg /mnt/loop/syslinux/syslinux.cfg

* Mount ISO
# mount -o ro /tmp/out/archlinux-2011.11.25-netinstall-i686.iso /mnt/iso

* DHCP/HTTP method
# dnsmasq --port=0 \
        --dhcp-range=,,8640 \
        --dhcp-boot=boot/syslinux/gpxelinux.0, \
        --dhcp-option-force=209,boot/syslinux/archiso.cfg \

* DHCP/TFTP method
# dnsmasq --port=0 \
        --enable-tftp \
        --tftp-root=/mnt/iso \
        --dhcp-range=,,8640 \
        --dhcp-boot=/arch/boot/syslinux/gpxelinux.0, \
        --dhcp-option-force=209,boot/syslinux/archiso.cfg \

* HTTP server
# darkhttpd /mnt/isolinux
