Upgrading my TrueNAS Mini X+ from TrueNAS Scale 23.10.2 to 24.04.0 was smooth.
I had to change the location of the node_exporter program from /usr/bin to a new location, which is under a separate dataset I created for local apps (not to be confused with the TrueNAS Scale Applications dataset).
The /usr directory, which is mounted from boot-pool/ROOT/24.04.0/usr, is now mounted as read-only.
