Hi, this is probably because you set UID & GID.
@Meierschlumpf anything we can do about this?

These are the default settings for the TrueNAS app and appear to be mandatory

We don't have any control over how TrueNAS implements Homarr. When you use GID and UID, which is what is going on here, there can be a significant waiting time, because the container needs to chown many small files. Ensure that Homarr is running on fast SSDs.
We will check whether we can optimise this further somehow (we already did optimise this step) but there will always be an additional startup time when using these flags.
See https://homarr.dev/docs/advanced/running-as-different-user/

I agree though, 10 minutes is insane and we usually saw about 10-20 seconds on our development machines. So there's definitely something going on that we're not aware of.

It would be interesting to see, whether this issue is TrueNAS exclusive or also happens on other systems when you use a different user. Please comment if you have any insights on this.

I think we first need more details before we can investigate anything here. Locally it always took about 10 seconds (thats also the reason we write it in the logs). It's really weird that truenas takes so long

In my own testing its easily reproducible on Electric Eel by installing the homarr app from the Truenas interface and starting it with the default settings. I had the same results on a fresh ixVolume as well as attempting to use my existing hostpath filestructure from my pre 1.0 homarr install.
