Glabel can create both transient and permanent labels: "glabel create label provider" is transient; "glabel label label provider" is permanent. In the latter case, the label metadata is stored in the last sector of "provider." If geom_label is built into the kernel, or loaded as a kernel module at boot (e.g., via /boot/loader.conf) then labelled providers will be automagically discovered and /dev/label/... entries created during boot. In this way, devices can be given logical labels that will stick with them when they move around.
