If you need /etc/passwd, for example, the better way is to 
$ grep username /etc/passwd > /path/to/croot/etc/passwd

but not to copy the whole /etc/passwd. If you needed shared library 
for elf32 binary file you can use ldd_handle.pl script. For shell script 
it's quite difficult to determine what external (not shell builtin ) command needed.
Probably you have to call ldd_handle.pl for each external binary file. I
think the one solution for such cases does not exists. But I think
the better it's just chrooted only needed files from packages like fileutils, but not
the whole package (why you need command like ls, dir? it's potential
security hole, IMHO)

PS: I wrote alternative, not replace for makejail and debootstrap.
