\cprotect\note{

   This directory contains \textbf{var}iable (or
   \textbf{volatile}) data files that change frequently during
   system operation Obviously \filelink{/var} cannot be mounted
   as a read-only filesystem.  For security reasons, it is
   often considered a good idea to mount \filelink{/var} as a
   separate filesystem.  Furthermore, if the directory gets
   filled up it should not lock up the system.

   \filelink{/var/log} is where most of the log files are
   located. \filelink{/var/spool} is where local files for
   processes such as mail, printing, and cron jobs are stored
   while awaiting action.
