       pmsd  -  Periodically  Manic  System  Daemon.  Manages  the bizzare and
       sometimes unexplainable behavior exhibited by computers.


       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  display 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

       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  activation of all command-line switches. This is to
              be avoided.

       -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 alt.flame.


       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?
