Turns out the easy solution was not to map it using the provided volumes like /mnt/truenas:/download but to just setup a new volume in each of them which solved the issue.
Document all your changes and all your methods
My friends joke with me that my notebook looks like a methwizards spell book from all the notes and notes on notes and dog eared notes. Nothing like having something fail two times and then work the third and you got no idea why unless you wrote down everything.
And don't listen to the disgruntled old-timers that say you'll stop exploring in your free time, they're just jealous and/or have kids with very little free time left.
Fuck that. I am in my 40's and still messing around with my lab and stuff in my free time...and at work. The want to learn never stops if you like what you are doing.
Not many I know of use it but they at least know what it is. However saying yes I understand how a type 1 hypervisor works is good enough.
I landed a job also just off my homelab. Well sitting in the interview I setup an account for the guy, got him accessed in and let him look at everything I did and could do. You would be amazed how much better it is to be able to show you can do a job then just try to tell someone you can.
Also it's a huge thing to show a willingness and gift for self learning, a lot of people do not have that. When you find someone like that even if the skills are raw you know that person can be turned into something great.
Never heard of symfonium, I'll need to google it.
