 Documentation for select files from the containers repo is below.
 
-**setup/hv/bootstrap** - This is the file that gets executed as the DETER start_cmd on the pnodes once the experiment is swapped in. It reads the experiment-specific conf file then sets up the local containers working directory (in {{{/share/containers}}). It then installs various packages, both for DETER and platform specific things ("deter_data" and a VDE build). It then runs {{{var/containers/setup/hv/hv}}} to do actual work. This file is described below.

 **/var/containers/setup/hv/hv** - This script is invoked by the start_cmd script on the pnode after the node has booted and before the containers are up. It untars the ${EXP}/containers dir into {{{/var/containers/config}}} and writes the /etc/{init,init.d} containers control/start/stop script. It then reads the {{{children}}} file. It then calls the per-child setup script ({{/setup/hv/*}}} (although I don't see these). Finally it invokes the /etc/init/containers platform script. (On Ubuntu it uses "start containers".) This maps to /var/containers/launch/hv/hv, described below.
