tizian - better chrooting with containers

Install

To install it run:

make
sudo make install

It's possible to disable AppArmor and S.A.R.A. by passing respectively NO_APPARMOR=1 and NO_SARA=1 to make.

To uninstall it run:

sudo make uninstall

If you are on Debian/Ubuntu, you can also build a .deb package:

make deb
sudo dpkg -i pkgs/tizian_*.deb

                                                it doesn't need to be unique across containers
                                                (default: '10.0.0.').
-c, --cpu-shares CPU_SHARES                     Minimum numbers of cpu shares (1024 == 1 cpu)
                                                for this container when system is busy (default:
                                                256).
-C, --cpu-perc CPU_PERC                         Maximum cpu usage percentage even when system is
                                                idle (default: 50).
-b, --blkio-weight BWEIGHT                      blkio CFQ weight (default: 0 - disabled).

-E, --init-cmd INIT_CMD                         The init program to run (default: a minimal built-in
                                                init process).
-P, --init-profile APPARMOR_PROFILE             AppArmor profile for init (default: 'tizian_init', use 'none' to

-U, --userns-slot SLOT                          UID and GID map slot. Available slots are form 0 to 65536.
                                                The slot is multiplied by 65535 to get the UID/GID map

Example:
        tizian create ~/chroot
