# Chroot Jail for SSH Access 
# Tested on Ubuntu 14.04.2 LTS and Debian GNU/Linux 8 (jessie)

# Reference : http://allanfeid.com/content/creating-chroot-jail-ssh-access
# 
# Had to add/change several things to make it work, including:
# - create lib64 folder
# - copy whoami dependencies that ldd doesn't show to fix 'I have no name!'
#   in the customized prompt + create passwd file
