       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 onproductionmachines; 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 automatically.


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