`/etc/bootc/config.toml` is not used by `bootc` binary

Hi there.

I'm trying to use system-upgrade-controller to upgrade kubernetes cluster with bootc-based nodes. System-upgrade-controller uses privileged container and mounts hosts' / into the containers' /host, which means executing bootc upgrade inside this container fails (bootc expects /sysroot/ostree to be present, although in this case it is /host/sysroot/ostree).

To overcome this I tried to use bootc's config.toml as described in the https://github.com/bootc-dev/bootc/blob/main/docs/src/man/bootc-config.5.md. Although I'm still getting a message that System is not deployed via bootc.

Here is my /etc/bootc/config.toml:

bash-5.1# cat /etc/bootc/config.toml
[storage]
root = "/host/sysroot/ostree/"

Am I doing something wrong here?

Thanks!

I don't really think configuration file /etc/bootc/config.toml is current implemented. It's nowhere mentioned in the source code and probably a pending feature at this stage.

Currently I think /sysroot/ostree is just hard-coded into the code base
