PMSD(8)                                                   PMSD(8)

       pmsd  - Periodically Manic System Daemon. Manages the biz­
       zare and sometimes  unexplainable  behavior  exhibited  by

       pmsd [-bcfmp]

       pmsd  is  a rogue daemon that is spawned on a semi-regular
       schedule by init(8).   Most  of  the  unusual  and  quirky
       behavior  associated  with  misbehaving  computers  can be
       attributed to pmsd.

       pmsd has a number of command-line options, invoked at run-
       time by init(8).  The ps(1) command will occasionally dis­
       play the current options, but  only  if  pmsd  feels  like
       revealing  them. This is usually not the case. pmsd can be
       manually invoked by the pms(8) command. Make sure there is
       not  a  pmsd  process already running when you use pms(8);
       you don't want to be on a system with  multiple  instances
       of pmsd running.

       With  no  flags, pmsd runs with the default -m option, and
       any others it feels like using.

       -b     Bloat. Files randomly  grow  in  size,  filling  up
              filesystems and causing quotas to be exceeded.

       -c     Craving.  System  becomes  hungry,  eating magnetic
              tapes, CD-ROM discs, floppies, and anything else  a
              hapless user loads into a removable media drive.

       -f     Fatigue.  System  will pause for a random period of
              time. It is important to  leave  the  system  alone
              during this time. Attempts to coax the machine into
              normal operation could cause the spontaneous  acti­
              vation  of all command-line switches. This is to be

       -m     Mood swings. Process priorities and nice values are
              altered  randomly.  Swapping usually occurs with no
              warning, even when memory is available. This is the
              default behavior.

       -p     Peeved.  One  or more users are selected as targets
              of the system's anger.  Files are  deleted,  e-mail
              copied to /etc/motd, and any Usenet articles posted
              by the targets are  crossposted  to  misc.test  and

       When  pmsd  is  invoked  by using the pms(8) command, pmsd
       ignores any command-line switches and does what it  damned
       well pleases.


       There are no bugs; how could you ask that?
