Понадобилось собрать систему для железки на стационарнике. Для возможности запуска ARM'овских бинарников используется QEMU, в полном соответствии со статьёй.
Файлы выполняются, о чём говорит следующее:

Судя по логу, оно не может найти /bin/bash. Но он же есть! Это подтверждается попыткой его прямого запуска (
Везде пишут, что подобная ошибка вылазит при неустановленном qemu-user, но он-то у меня стоит:
Консоль:
andreilPC root # ls -l usr/bin/qemu-static-armeb*
-rwxr-xr-x 1 root root 3196136 май 28 08:44 usr/bin/qemu-static-armeb
-rwxr-xr-x 1 root root 1825424 май 28 08:44 usr/bin/qemu-static-armeb-binfmt

-rwxr-xr-x 1 root root 1825424 май 28 08:44 usr/bin/qemu-static-armeb-binfmt
Никак не могу понять, ЧЯДНТ
PS: В папке "root" лежит содержимое архива "stage3-armeb-uclibc-softfloat-2005.1.tar.bz2", скачанного с официального репозитория - то, что надо для моей железки...
PPS: Попытка выполнить chroot с полным путём к каталогу не предлагать - тот же результат:
Консоль:
andreilPC root # chroot /media/work/Dev/ARM/NAS/root/
chroot: failed to run command ‘/bin/bash’: No such file or directory
