-These things will change in future udev versions:
- o log warning if the kernel uses CONFIG_SYSFS_DEPRECATED*=y,
- which means that /sys/class/block/ does not exist
- o DEVTYPE for disks is set by the kernel, they will be removed from
- the default rules
- o "udevadm control" commands will only accept the --<command> syntax
- o symlink names to udevadm will no longer be resolved to old command names
