332 and all blocks are packed to minimise data overhead. Block sizes
333 greater than 4K are supported up to a maximum of 1 Mbytes (default

503 If you only intend to mount files from some other Unix over the
504 network using NFS, you don't need the System V file system support
505 (but you need NFS file system support obviously).
506
507 Note that this option is generally not needed for floppies, since a
508 good portable way to transport files and directories between unixes
509 (and even other operating systems) is given by the tar program ("man
510 tar" or preferably "info tar"). Note also that this option has
511 nothing whatsoever to do with the option "System V IPC". Read about
512 the System V file system in
