Добавил strace, пакетик livecd-qemu-arch с конфигурацией apt
для arm/ppc и скриптиками для binfmt_misc, положил hasher-priv
с патчиком насчёт QEMU_STRACE=1:

http://ftp.linux.kiev.ua/pub/Linux/ALT/people/mike/iso/mkimage-profiles/tmp/live-builder-20120801-x86_64.iso

Тестировал на VM с 4Gb RAM и доступом в интернет:

tty2 # register-qemu-ppc
tty2 # cat /proc/sys/fs/binfmt_misc/ppc

tty3 $ cd /usr/share/mkimage-profiles
tty3 $ make ARCH=ppc APTCONF=/etc/apt/apt.conf.4.1.ppc ve/bare.tar
