In Scale and Core before, it was possible using the shell and using → usermod. That’s why certain users are member of certain groups right now. But today this feature has gone. root@truenas[/home/admin]# usermod -aG group user [sss_cache] [confdb_init] (0x0010): Unable to open config database [/…

That is very inconvenient. It has worked for 100 years.

+1 to this being a terrible idea. Make it a multi click process with more annoying visual verification if you’re worried about inexperienced users making system-breaking changes but you need to still allow your veteran users the ability to do what they need to do. Taking this function away was a po…

If it can tip the balance, might as well try! I want to install the application “Automatic Ripping Machine” on my NAS. This application watches the CDROM drive and automatically rip music or movies. The problem is that, even if I mount the cdrom into the container, the running application does not …

Hah - maybe this is why I could not get Automatic Ripping Machine to work, there is no access to /dev/sr0 by the apps user and I cannot add it to the cdrom group. EDIT: No, chmod +444 /dev/sr0 did not fix my problems :frowning: Fri Sep 5 13:47:43 CEST 2025 Entering docker wrapper Fri Sep 5 13:47…

I mostly use ARM for music, but the issue I’m facing is that the UI does not shows any drives, but I figured out a “little dance” to make it show up and rip audio CDs. EDIT: No, chmod +444 /dev/sr0 did not fix my problems :frowning: No, you’re right. I was on a false track. I opened a bug into t…

I tried a different one - same issue. Here someone suggests a very peculiar method to solve this issue. Since the TrueNas app does not really allow me to set the --cap-add docker flag I am not sure if this is possible Disk is not found · automatic-ripping-machine/automatic-ripping-machine · Discussi…

This prevents using the ssh, docker, and systemd-journald groups for basic security and troubleshooting, which is silly and depressing. I’m sure there are many other use cases this change could easily interfere with. Please revert. Also I don’t see any mention on Fangtooth’s changelog regarding bui…

@awalkerix Any updates on this? This change makes managing group membership inconvenient at best.

Yeah it also breaks LXC GPU passthrough because you can’t add users to the render group anymore. Will have to try getting it to run in a privileged container now. I get that they want to add guardrails around built-ins but you have to add users to some of these groups to make use of your hardware.

Excuse me if I’m completely ignorant… I’m new to Scale (I just migrated from TrueNAS Core.) Why can’t you create a custom user and include the necessary builtin groups as auxiliary groups in the user profile? Then you can tweak the user profile as you wish. Of course, then you have to adjust perm…

No, the only issue i had was that incus mounts the gpu to a different directory then exected by docker so you have to fix that as explained in the link below
