Yes, good idea.
bcm91250a-be space # strace -o output.strace chroot
/space/catalyst/tmp/default/stage1-mips4_n32-20101114/tmp/stage1root/
/bin/bash
chroot: failed to run command `/bin/bash': No such file or directory
It actually reports
execve("/bin/bash", ["/bin/bash"], [/* 27 vars */]) = -1 ENOENT (No
such file or directory)
But what the heck?
