I find it an interresting problem, but I it is beyond my current knowledge. I even don't know if it could work, but *lets assume* that the OpenWRT kernel plus OpenWRT userland can "chroot into" Debian userland. > # uname -a > Linux netgate 126.96.36.199 #1 Tue Sep 6 09:58:59 CEST 2011 mips GNU/Linux > > # file /bin/busybox > /bin/busybox: ELF 32-bit MSB executable, MIPS, MIPS32 rel2 version 1, dynamically linked (uses shared libs), corrupted section header size > > # file /chroot/bin/ls > /chroot/bin/ls: ELF 32-bit MSB executable, MIPS, MIPS-II version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.26, with unknown capability 0x41000000 = 0xf676e75, with unknown capability 0x10000 = 0x70401, stripped How 'MIPS32 rel2 version 1' relates to 'MIPS-II version 1 (SYSV)' is unknown to me. > # cat /proc/cpuinfo > system type : Atheros AR7161 rev 2 > machine : NETGEAR WNDR3700 > processor : 0 > cpu model : MIPS 24Kc V7.4 > BogoMIPS : 452.19 <snip/> > As I understand the problem is a "binfmt thingy". Sorry, I can't explain it. This is partial output of 'aptitude show binfmt-support' allows system administrators to register interpreters for various binary formats based on a magic number My advice is to play with OpenWRT kernel configuration for "binfmt".
