fakechroot runs a command in an environment were is additional possibility to
use chroot(8) command without root privileges. This is useful for allowing
users to create own chrooted environment with possibility to install another
packages without need for root privileges.
fakechroot replaces some libc library functions (chroot(2), open(2), etc.)
by ones that simulate the effect of being called with root privileges.
These wrapper functions are in a shared library
/usr/lib/fakechroot/libfakechroot.so which is loaded through the
LD_PRELOAD mechanism of the dynamic loader. (See ld.so(8))
In fake chroot you can install Debian bootstrap with debootstrap command. In
this environment you can use i.e. apt-get(8) command to install another
packages. You don't need a special privileges and you can run it from common
user's account.
