MAKEDEV — create
system and device special files
The shell script MAKEDEV, found in the
/dev directory, is used to create various special
files. See intro(4) for a more
complete discussion of special files.
MAKEDEV takes any number of device names
as arguments, where the names are the common abbreviation for the device or
group of devices.
Where a device name is followed by a star ‘*’, the
star must be replaced by a unit number. If units are expected for a device
but not provided, MAKEDEV will supply the standard
numbers in most cases.
The amd64 supports the following devices:
Special device names
- all
- Creates special files for all devices on amd64.
- ramdisk
- Ramdisk kernel devices.
- std
- Creates the ‘standard’ devices (console, klog, kmem, ksyms,
mem, null, stderr, stdin, stdout, tty, zero) which are absolutely
necessary for the system to function properly.
- local
- Creates configuration-specific devices, by invoking the shell file
MAKEDEV.local.
