Well, the command name should probably be _post_ chroot i.e. /bin/bash,
not /home/login/bin/bash (remember - the chroot will be calling execve()
_after_ chroot()ing).
Also, one of the many pleasures of chroot jails is that you need to put
all the needed shared libraries in the chroot jail so dynamicly linked
programs can find them. "ldd /bin/bash" on my system says:
[~]amadeus*> ldd /bin/bash
libtermcap.so.2 => /lib/libtermcap.so.2 (0x40032000)
libdl.so.2 => /lib/libdl.so.2 (0x40036000)
libc.so.6 => /lib/libc.so.6 (0x4003a000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
so you also need a fake /lib in the jail with hardlinked (or copied)
instances of these library files. And so on.
