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).
