In that case I think it's best to use
post_command += " python scripts/check_image.py;"
because when commands are separated by ';', the returned exit status is
that of the last command (at least according to my little check).
However, check_image.py must be the last command in the series, so no
other commands should be appended to post_command after it. If
additional commands are needed they should be pre-pended using <=.
The current way of defining post_command is a little limited. If we
find out that we need to create complex combinations of commands, some
of which are critical and some of which are not, we may want to start
defining commands like we define VMs:
post_commands = cmd1
command_cmd1 = ls
command_critical_cmd1 = no
command_timeout_cmd1 = 10
...
post_commands += " check_image"
command_check_image = python scripts/check_image.py
command_critical_check_image = yes
command_timeout_check_image = 60
This offers a lot of flexibility but is also uglier.
