NAME

       chroot_package_run - repeat a program within the package with the help of chroot

SYNOPSIS

       chroot_package_run --package-path your-package-path [command]

DESCRIPTION

       If  chroot  is  used  to  help repeat one experiment, common directories like /proc, /dev,
       /net, /sys, /var, /misc and /selinux will be remounted into the package if they exists  on
       your  local  filesystem.  After  you finish all your test within chroot_package_run, these
       remounted directories will be unmounted. If no command is given, a /bin/sh shell  will  be
       returned.

OPTIONS

        -p, --package-path
              The path of the package.

        -e, --env-list
              The  path  of  the  environment  file, each line is in the format of <key>=<value>.
              (Default: package-path/env_list)

        -h, --help
              Show this help message.

EXIT STATUS

       On success, returns zero. On failure, returns non-zero.

EXAMPLES

       To repeat one program within one package /tmp/package in a bash shell:

               % chroot_package_run --package-path /tmp/package /bin/bash

       After the execution of this command, one shell will be returned, where you can repeat your
       original program. After everything is done, exit chroot_package_run:

               % exit

       You  can  also  directly  set your command as the arguments of chroot_package_run. In this
       case, chroot_package_run will exit automatically after the command is finished, and you do
       not  need  to  use exit to exit. However, your command must belong to the original command
       set executed inside parrot_run and preserved by parrot_package_create.

               % chroot_package_run --package-path /tmp/package ls -al

       Here is a short instruction about how to make use of parrot_run, parrot_package_create and
       chroot_package_run  to generate one package for your experiment and repeat your experiment
       within your package.

       Step 1: Run your program under parrot_run and using --name-list and --env-list  parameters
       to record the filename list and environment variables.

               % parrot_run --name-list namelist --env-list envlist /bin/bash

       After  the  execution  of this command, you can run your program inside parrot_run. At the
       end of step 1, one file named namelist containing all the accessed file names and one file
       named  envlist  containing  environment  variables will be generated.  After everything is
       done, exit parrot_run:

               % exit

       Step 2: Using parrot_package_create to generate a package.

               % parrot_package_create --name-list namelist --env-path envlist --package-path /tmp/package

       At the end of step 2, one package with the path of /tmp/package will be generated.

       Step 3: Repeat your program within your package.

               % chroot_package_run --package-path /tmp/package /bin/bash

       After the execution of this command, one shell will be returned, where you can repeat your
       original program. After everything is done, exit chroot_package_run:

               % exit
