non-native ARM support via qemu mkimage and hasher can make use of qemu to run non-native binaries while working on the chroots; thanks kas@, manowar@ and sbolshakov@ for implementing this functionality as well as providing nice examples through mkimage-profiles-arm and mkimage-profile-armrootfs. This required the architecture check to be added since baking a tarball with "arm" as its specified arch and x86_64 inside isn't particularly good thing to let slip through; however the implementation is quite fragile, bugreports and patches are seriously welcome. NB: APTCONF evaluation order between lazy make and nimble shell turned out to be quite a delicate issue in this particular case.

Для сборки с применением трансляции посредством QEMU
выполните от имени root следующие команды:
apt-get install qemu-user-binfmt_misc
modprobe binfmt_misc
echo 32768 > /proc/sys/vm/mmap_min_addr
initial PowerPC support As it happens, adding another architecture required almost no changes; native 32-bit ppc build took only ARCH and a repo, qemu-ppc one still has problems (/.host/entry hangs while unpacking setup for fakedata). Proof of concept on a QS22: $ make ve/bare.tar.gz ** ARCH: ppc /bin/sh: rpmvercmp: command not found 21:41:01 cleaning up 21:41:03 initializing BUILDDIR: build/ 21:41:03 preparing distro config 21:41:05 starting image build (coffee time) 21:42:48 done (1:42) ** image: $TMP/out/bare-20120716-ppc.tar.gz [21M]

Если файл /proc/sys/fs/binfmt_misc/register не существует,
потребуется установить и загрузить иное ядро (например, std-def).

Также нужен sources.list с указанием соответствующего репозитория
и ссылающийся на него apt.conf (см. apt.conf.sample); например:
