When I execute x86-program(builded with dynamic libraries) in lxc
container, it shows:
"bash: x86-program: No such file or directory"
Obviously, the container has not called the right dynamic
linker(ld-linux.so) to interpret the x86-program.
Maybe I could register this linker or the linker wrap to
/proc/sys/fs/binfmt_misc ?
