       xfs.options - configuration options for the X font server


       /etc/X11/fs/xfs.options contains a set of flags that determine some of the behavior of the
       X font server xfs(1).

       /etc/X11/fs/xfs.options may contain comments, which begin with a hash mark (‘#’)  and  end
       at  the  next newline, just like comments in shell scripts.  The rest of the file consists
       of options which are expressed as words separated by hyphens, with  only  one  option  per
       line.   Options  are  enabled  by  simply  placing  them in the file; they are disabled by
       prefixing the option name with ‘no-’.

       Available options are:

              Enable this option with caution on ‘production’ machines; it causes the xfs  daemon
              to  be  stopped and restarted on upgrade.  This will break all existing connections
              by X servers to the font server, and as a result may  deprive  them  of  access  to
              fonts.   In  some situations this could be an unwelcome surprise (for instance, for
              remote  xfs  users  who  had  no  idea  the  administrator  was  performing  system
              maintenance).   On  the  other  hand, for machines that stay up for long periods of
              time, leaving the old daemon running can be a bad idea if the new version has,  for
              instance,  a  fix for a security vulnerability (overwriting xfs's executable on the
              file system has no effect on the copy of xfs in memory).  This behavior is disabled
              by default: xfs will be not be stopped or started during an upgrade of its package;
              the administrator will have to do so by hand (with invoke-rc.d xfs  restart  or  by
              rebooting the system) before the newly installed xfs binary is used.

       Since   no  options  are  enabled  by  default,  /etc/X11/fs/xfs.options  is  not  created


       Branden  Robinson  customized  xfs's  package  maintainer   scripts   to   implement   the
       functionality described above.
