Here's what I do: Grab the binaries tarball from http://www.landley.net/code/firmware/broken.tbz (this is about 650k compressed, and 1.3 megs uncompressed).
Extract it, and remember where it is. Build UML, as follows: tar xvjf linux-2.6.13.2.tar.bz2 cd linux-2.6.13.2 make ARCH=um allnoconfig cat >> .config << EOF CONFIG_MODE_SKAS=y CONFIG_BINFMT_ELF=y CONFIG_HOSTFS=y CONFIG_STDERR_CONSOLE=y CONFIG_UNIX98_PTYS=y CONFIG_BLK_DEV_LOOP=y CONFIG_LBD=y CONFIG_PROC_FS=y EOF yes "" | make ARCH=um oldconfig make ARCH=um Run this UML via: ./linux rootfstype=hostfs rw init=/bin/sh LD_ASSUME_KERNEL=2.4.1 And now run the test: chroot /path/to/broken /test.sh An example run on my laptop: chroot /home/landley/newbuild/firmware-build-0.8.1/broken /test.sh /busybox install -c test.sh /sub/1 /busybox install -c test.sh /sub/2 /busybox install -c test.sh /sub/3 /busybox install -c test.sh /sub/4 /busybox install -c test.sh /sub/5 /busybox install -c test.sh /sub/6 /busybox install -c test.sh /sub/7 /busybox install -c test.sh /sub/8 /busybox install -c test.sh /sub/9 /busybox install -c test.sh /sub/10 /busybox install -c test.sh /sub/11 /busybox install -c test.sh /sub/12 /busybox install -c test.sh /sub/13 install: unable to open `/sub/13/test.sh': No such file or directory install: cannot change permissions of /sub/13/test.sh: No such file or directory install: cannot change ownership of /sub/13/test.sh: No such file or directory sh-3.00# It's possible that busybox or uClibc is doing something wrong, but this is _rock_solid_ on a normal kernel, and on 2.6.11-um (under -tt mode, anyway). On 2.6.13, this happens in both -tt mode and -skas0 mode. Help?
