                      3: dmsdosd \- dmsdos daemon for background compression
                      4: .SH SYNOPSIS
                      5: 
                      6: .BI dmsdosd " directory [level [debug]]"
                      7: 
                      8: .SH DESCRIPTION
                      9: .I dmsdosd 
                     10: does compression for the dmsdos driver in the background when
                     11: the system is idle. This may reduce system load when there are much data
                     12: to compress because the dmsdos driver can leave the data as they are and
                     13: pass them to the daemon to do the job of compression.
                     14: .I directory
                     15: must be the mountpoint of a CVF that is served by dmsdos.
                     16: In fact,
                     17: .I directory
                     18: may be also a subdirectory of the mountpoint. (If you mount more than
                     19: one dmsdos partition it doesn't matter which one you specify. There is
                     20: also no need to restart the daemon when additional partitions are mounted -
                     21: the daemon automatically handles them all.)
                     22: 
                     23: .I level
                     24: is the compression level. It must be in the range of
                     25: .BR 1 " - " 12 .
                     26: If no
                     27: .I level
                     28: is given, it defaults to 12.
                     29: 
                     30: If the parameter
                     31: .I debug
                     32: is given, dmsdosd prints a lot of debug information to stderr and doesn't
                     33: put itself into the background.
                     34: 
                     35: Note that you must run
                     36: .I dmsdosd
                     37: as root. The daemon refuses to run if started by another user. It also
                     38: doesn't start if it finds already one instance of
                     39: .I dmsdosd
                     40: running.
                     41: 
                     42: You can kill the daemon at any time (even when it is under heavy work).
                     43: Send a SIGINT to let the daemon finish its actual work and then exit.
                     44: Send a SIGTERM to make the daemon exit as soon as possible. You should not 
                     45: send a SIGKILL.

                     48: .I dmsdosd 
                     49: can only be started when a CVF has already been mounted by the
                     50: dmsdos driver. 
                     51: 
                     52: You must kill 
                     53: .I dmsdosd
                     54: before you can unmount the CVF that was given in the command line.
                     55: 
                     56: Older versions (below 0.9.0.12) didn't run in the background, didn't check 
                     57: for already running processes and didn't use stderr for error and debug
                     58: messages. This manual page is not valid for them.
