Update for issues with Proxmox 7.

- The eval{} block was originally returning a value that would allow
execution in the $@ conditional. This changed between Proxmox 6 and 7.
Why, no idea at the moment. Also, the original HASH was no longer valid
as a variable. I don't like the code block at this moment, I need to do
some regression testing to Proxmox 5 and FreeNAS/TrueNAS 11 and 12 to
see if I can clean up the conditional block. It was there for a reason I
just don't know at this moment.
