The check for the destination being a directory is now done before
checking if the file exists, that way the user is informed that the
thirsty argument is required.
If I create a database from scratch and assign permissions by doing:
- name: ensure database is created
action: postgresql_db db=$dbname
- name: ensure django user has access
action: postgresql_user db=$dbname user=$dbuser priv=ALL password=$dbpassword
Then it fails with the error:

This fix fixes the problem by not executing the regex if the
db query on pg_database returns None.
The use-case here is that based on information in the /proc/cmdline certain actions can be taken.
A practical example in our case is that we have a play at the end of the provisioning phase that reboots the system. Since we don't want to accidentally reboot a system (or restart the network) on a production machine, having a way to separate an Anaconda post-install (sshd in chroot) with a normal system is a good way to make that distinction.
---
- name: reboot
hosts: all
tasks:
- action: command init 6
only_if: "not '${ansible_cmdline.BOOT_IMAGE}'.startswith('$')"
A practical problem here is the fact that we cannot simply check whether it is set or empty:
---
- name: reboot
hosts: all
tasks:
- action: command init 6
only_if: "'${ansible_cmdline.BOOT_IMAGE}'"
If ansible_cmdline was a string, a simple only_if: "'${ansible_cmdline}'.find(' BOOT_IMAGE=')" was an option, but still not very "beautiful" :-/
This implementation uses shlex.split() and uses split(sep, maxsplit=1).
This allows the use of ~ in the chdir argument of the command module
I know the later change is absolutely necessary as the first change
was not sufficient. It may be that the first change fixes shell and
the second fixes command.
Added required as optional argument to get_bin_path(). It defaults to
false. Updated following modules to use required=True when calling
get_bin_path(): apt_repository, easy_install, group, pip,
supervisorctl, and user.
Also removed _find_supervisorctl() from supervisorctl module and updated
_is_running() to not need it.
