I guess it should so and with ptxdist it is also more or less easy to adjust the correct settings.

But when I mount the rootfs.jffs2 on my Pc I see all directories (bin/, sbin/, etc/ , ....) and all the commands are build in and linked to busybox.

file test/bin/busybox

test/bin/busybox: setuid ELF 32-bit LSB shared object, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.23, stripped

Unfortunately I have done some bad changes that the rootfs is no longer been mounted on startup :-(
