Hay un script que se llama MAKEDEV, ¿probaste de usarlo?
MAKEDEV(8)                                 Linux Programmer's 
Manual                                 MAKEDEV(8)

NAME
      MAKEDEV - create devices

SYNOPSIS
      cd dev; ./MAKEDEV -V
      cd dev; ./MAKEDEV [ -n ] [ -v ] update
      cd dev; ./MAKEDEV [ -n ] [ -v ] [ -d ] device ...

DESCRIPTION
      MAKEDEV is a script that will create the devices in /dev used to 
interface with drivers in the kernel.

      This  man page is woefully out of date.  A large number of 
devices are supported that are not documented
      here.

      Note that programs giving the error ``ENOENT: No such file or 
directory'' normally means that the device
      file  is  missing, whereas ``ENODEV: No such device'' normally 
means the kernel does not have the driver
      configured or loaded.

OPTIONS
      -V     Print out version (actually RCS version information) and exit.

      -n     Do not actually update the devices, just print the actions 
that would be performed.

      -d     Delete the devices.  The main use for this flag is by 
MAKEDEV itself.

      -v     Be verbose.  Print out the actions as they are performed.  
This is the same output as produced by
             -n.

CUSTOMISATION
      Since  there  is  currently no standardisation in what names are 
used for system users and groups, it is
      possible that you may need to modify MAKEDEV to reflect your 
site's settings.  Near the top of the  file
      is  a  mapping from device type to user, group and permissions 
(e.g. all CD-ROM devices are set from the
      $cdrom variable).  If you wish to change the defaults, this is 
the section to edit.

DEVICES
      General Options

      update This only works on kernels which have /proc/interrupts 
(introduced during 1.1.x).  This  file  is
             scanned  to  see what devices are currently configured 
into the kernel, and this is compared with
             the previous settings stored in the file called DEVICES.  
Devices which are  new  since  then  or
             have  a different major number are created, and those 
which are no longer configured are deleted.

      generic
             Create a generic subset of devices.  This is the standard 
devices, plus  floppy  drives,  various
             hard drives, pseudo-terminals, console devices, basic 
serial devices, busmice, and printer ports.

      std    Standard devices.  These are: mem - acess to physical 
memory; kmem -  access  to  kernel  virtual
             memory;  null  - null device (infinite sink); port - 
access to I/O ports; zero - null byte source
             (infinite source); core - symlink to /proc/kcore (for 
kernel debugging); full  -  always  returns
             ENOSPACE on write; ram - ramdisk; tty - to access the 
controlling tty of a process.

      local  This simply runs MAKEDEV.local.  This is a script that can 
create any local devices.

      Virtual Terminals

      console
             This  creates the devices associated with the console.  
This is the virtual terminals ttyx, where
             x can be from 0 though 63.  The device tty0 is the 
currently active vt, and is also known as con­
             sole.  For each vt, there are two devices vcsx and vcsax, 
which are used to generate screen-dumps
             of the vt (the vcsx is just the text, and vcsax includes 
the attributes).


Con respecto a lo de instalar una sola vez, es muy cierto, todo problema 
tiene solución sin reinstalar (¿seré un fanático?)
