NAME
     partition_map - tell rpc.ttdbserverd(1M) to locate its data-
     bases in an alternate file system

SYNOPSIS
     partition_map

DESCRIPTION
     For each filesystem  that  rpc.ttdbserverd  needs  to  store
     information  about,  it  creates a directory called TT_DB at
     the mountpoint of that file system.  In  that  directory  it
     creates  the  databases  it  needs  to  store its tables and
     indices.   If  the   partition   is   not   writable,   then
     rpc.ttdbserverd can be told, via partition_map(4), to create
     the databases in another file system.

     The partition_map file is called "partition_map" and resides
     in  /etc/tt.   If  $TT_PARTITION_MAP  is  set, it is used in
     place of /etc/tt/partition_map.

     rpc.ttdbserverd(1M) reads the partition map upon startup and
     rereads the map if it receives signal USR2.

  Format rules
     The format rules for a partition_map are:

     1. Any line beginning with a "#" or white-space and a "#" is
        a comment.

     2. Blank lines are comments.

     3. Words are delimited by white space.

     4. The first word in a non-comment  line  is  the  partition
        from which to map.

     5. The second word in a non-comment line is the partition to
        which  to  map.  Although  the  TT_DB  directories are by
        default at the root of their file systems, the  user  may
        in  fact  map  to any local filename that is writeable by
        UID root.

ENVIRONMENT
     TT_PARTITION_MAP
          If $TT_PARTITION_MAP is set, it is  used  in  place  of
          /etc/tt/partition_map.

EXAMPLES
     This example maps "/cdrom" to "/usr":


          # cannot write to /cdrom
          /cdrom /usr

     This example maps "/cdrom" to "/usr/TT_maps/cdrom":


          # cannot write to /cdrom
          /cdrom /usr/TT_maps/cdrom
