Making devices
Note that unpacking the MAKEDEV-&makedev-version;.bz2
file doesn't create a directory for you to cd into, as
the file contains only a shell script.
Install the MAKEDEV script:
bzcat MAKEDEV-&makedev-version;.bz2 > /dev/MAKEDEV
chmod 754 /dev/MAKEDEV
Run the script to create the device files:
cd /dev
./MAKEDEV -v generic-nopty
The meaning of the arguments:
-v: This tells the script to run in
verbose mode.
generic-nopty: This instructs
MAKEDEV to create a generic selection of commonly used
device special files, except for the ptyXX and ttyXX range of files. We don't
need those files because we are going to use Unix98 PTYs via the
devpts file system.
If it turns out that some special device zzz that
you need is missing, try running ./MAKEDEV -v zzz.
Alternatively, you may create devices via the mknod
program. Please refer to its man and info pages if you need more
information.
If you wish your system to be FHS-compliant, then the
MAKEDEV script has to remain present in the
/dev directory. This way it is always
available for making extra device nodes.
Additionally, if you were unable to mount the devpts file system earlier
in , now is the time to try the alternatives. If
your kernel supports the devfs file system, run the following command to mount
devfs:
mount -t devfs devfs /dev
This will mount the devfs file system over the top of the new static
/dev structure. This poses no problems, as the device nodes
created are still present, they are just hidden by the new devfs
file system.
If this still doesn't work, the only option left is to use the MAKEDEV
script to create the ptyXX and ttyXX range of files that would otherwise not be
needed. Ensure you are still in the /dev directory then run
./MAKEDEV -v pty. The downside of this is, we are
creating an extra 512 device special files which will not be needed when we
finally boot into the finished LFS system.
