- 'makedevs' is a utility used to create a batch of devices with
- one command.
- .
- There are two choices for command line behaviour, the interface
- as used by LEAF/Linux Router Project, or a device table file.
- .
- 'leaf' is traditionally what busybox follows, it allows multiple
- devices of a particluar type to be created per command.
- e.g. /dev/hda[0-9]
- Device properties are passed as command line arguments.
- .
- 'table' reads device properties from a file or stdin, allowing
- a batch of unrelated devices to be makde with one command.
- User/group names are allowed as an alternative to uid/gid.

+ 'makedevs' is a utility used and created by the Linux Router Project.
+ It creates a large number of device special files (/dev devices)
+ rather quickly, and can be considerably faster then running mknod a
+ zillion times.
