mtools: miscellaneous flags

 
 3.5.6 General Purpose Drive Flags
 ---------------------------------
 
 A flag can either be set to 1 (enabled) or 0 (disabled). If the value is
 omitted, it is enabled.  For example, `scsi' is equivalent to `scsi=1'
 
 `nolock'
      Instruct mtools to not use locking on this drive.  This is needed
      on systems with buggy locking semantics.  However, enabling this
      makes operation less safe in cases where several users may access
      the same drive at the same time.
 
 `scsi'
      When set to 1, this option tells mtools to use raw SCSI I/O
      instead of the standard read/write calls to access the device.
      Currently, this is supported on HP-UX, Solaris and SunOS.  This is
      needed because on some architectures, such as SunOS or Solaris, PC
      media can't be accessed using the `read' and `write' system calls,
      because the OS expects them to contain a Sun specific "disk label".
 
      As raw SCSI access always uses the whole device, you need to
      specify the "partition" flag in addition
 
      On some architectures, such as Solaris, mtools needs root
      privileges to be able to use the `scsi' option.  Thus mtools
      should be installed setuid root on Solaris if you want to access
      Zip/Jaz drives.  Thus, if the `scsi' flag is given, `privileged'
      is automatically implied, unless explicitly disabled by
      `privileged=0'
 
      Mtools uses its root privileges to open the device, and to issue
      the actual SCSI I/O calls.  Moreover, root privileges are only
      used for drives described in a system-wide configuration file such
      as `/etc/mtools.conf', and not for those described in
      `~/.mtoolsrc' or `$MTOOLSRC'.
 
 `privileged'
      When set to 1, this instructs mtools to use its setuid and setgid
      privileges for opening the given drive.  This option is only valid
      for drives described in the system-wide configuration files (such
      as `/etc/mtools.conf', not `~/.mtoolsrc' or `$MTOOLSRC').
      Obviously, this option is also a no op if mtools is not installed
      setuid or setgid.  This option is implied by 'scsi=1', but again
      only for drives defined in system-wide configuration files.
      Privileged may also be set explicitly to 0, in order to tell
      mtools not to use its privileges for a given drive even if
      `scsi=1' is set.
 
      Mtools only needs to be installed setuid if you use the
      `privileged' or `scsi' drive variables.  If you do not use these
      options, mtools works perfectly well even when not installed
      setuid root.
 
 `vold'
      Instructs mtools to interpret the device name as a vold identifier
      rather than as a filename.  The vold identifier is translated into
      a real filename using the `media_findname()' and
      `media_oldaliases()' functions of the `volmgt' library.  This flag
      is only available if you configured mtools with the
      `--enable-new-vold' option before compilation.
 
 `swap'
      Consider the media as a word-swapped Atari disk.
 
 `use_xdf'
      If this is set to a non-zero value, mtools also tries to access
      this disk as an XDF disk. XDF is a high capacity format used by
      OS/2. This is off by default. XDF, for more details.
 
 `mformat_only'
      Tells mtools to use the geometry for this drive only for
      mformatting and not for filtering.
 
 `filter'
      Tells mtools to use the geometry for this drive both for
      mformatting and filtering.
 
 `remote'
      Tells mtools to connect to floppyd (floppyd).
