Followup~ Definite breaks some things in the HexOS deck dashboard.
Dash: Processor and Memory readings are completely incorrect (TrueNAS dashboard says processor is 2% while HexOS says its 98%, so I think it is flipped, showing unutilized CPU as utilized) and RAM is not showing any data on the HexOS side of things. The Network information seems to be accurate for up and down stream. HDD usage on HexOS and TrueNAS seem to be in conflict (though I didn't look at the difference before updating XD). HexOS states I have used 0.5 TB / 23.83 TB, while TrueNAS states it is 464.39 GiB / 21.22 TiB (granted, maybe TiB and TB are different units of measurement? not sure on that myself).
Folders: User creation and deletion works without a problem. Folder creation, deletion, and permission assignment works as well.
Storage: Cannot verify as I don't want to delete and remake my pool XD
Apps: Stop/Start works. Launch never worked for me before and still doesn't work. I uninstalled plex successfully. Reinstall was also successful.
Settings: All seems well here.
Final observation: Things are taking a bit more time to actually show up in the Deck dashboard for HexOS, but it is a difference of a few seconds longer. Obvious notes of "this is just my observation and applied to my setup with my hardware, etc... etc... etc...", so proceed at your own discretion XD For my case though, kinda sad the system utilization info is inaccurate on the Deck dash now, as it is nice to see that remotely, but it isn't the end of the world as I can check it at home from the TrueNAS UI.
