According commands/boot.c help message:

| "BOOTSRC can be:"
| "- a filename under /env/boot/"
| "- a full path to a boot script"
| "- a full path to a bootspec entry"
| "- a device name"
| "- a partition name under /dev/"
| "- a full path to a directory which"
| "   - contains boot scripts, or"
| "   - contains a loader/entries/ directory containing bootspec entries"

the 'full path' to a device is not suported yet. Should that be fixed
within the boot-cmd?
