update device nodes to reflect kernel configuration
/etc/conf/bin/idmknod [-o device-dir] [-r config-dir] [[-M module-name] ...]
[-s] [-d sdev] [-#]
One of the Installable Driver/Tunable Parameters configuration tools,
idmknod reconstructs nodes
(block and character special device files)
in /dev and its subdirectories,
based on the
files for currently configured modules
(those with at least one ``Y'' in their
files) for entry-type 0 drivers
(those with b or c in the
``characteristics'' field of their
Any nodes with major numbers corresponding to drivers
with a ``K'' flag set in the
characteristics fields of their Master file are
All other nodes will be removed or created as needed to
exactly match the configured Node files.
Any needed subdirectories are created automatically.
Subdirectories that become empty as a result of node removal
are removed, also.
All other files in the /dev directory tree are left
unchanged, including symbolic links.
idmknod takes the following options:
Install nodes in (or remove them from) the directory specified
rather than the default, /dev.
Use the directory specified, instead of /etc/conf,
as the root of the configuration data directories.
Suppress removing nodes; just add new nodes.
Make new nodes in /dev,
as specified in the node file
for the specified loadable kernel module.
Use the sdev file instead of
for current configuration information.
Print debugging information.
An exit value of zero indicates success.
If an error is encountered
due to a syntax or format error in a
entry, an advisory message is printed to
and the command execution continues.
If a serious error is encountered
(for example, a required file cannot be found),
exits with a non-zero value and reports an error message.
On the next system reboot after a kernel reconfiguration,
in sysinit state,
the idmknod command is run automatically (by idmkenv)
to establish the correct representation of device nodes in the
directory tree for the running kernel.
idmknod (with the -M option)
is called by idbuild when loadable kernel module
configuration is requested.
can be executed as a user level command to test modification of the
directory before a Driver Software Package (DSP) is built.
It is useful in installation scripts
that do not reconfigure the kernel, but that need to create
