#! /bin/bash

# I am exporting variables to have them in my shell after I ran the script. 
# I find that convenient. Of course, those can/should be removed in "serious" deployments.

# create a time string between "1:00" and "5:59"
export REBOOT_TIME=`perl -e "print scalar(int 1 + 5 * rand) . q[:] . scalar(int 6 * rand) . scalar(int 9 * rand)"`
export HOSTNAME=`hostname`
export NETWORK_DEVICE=eth0 # might be different in cloud servers
