　　util-linux 2.27 发布，此版本主要更新内容如下：

• 　　The command tailf is deprecated in favour of tail -f from coreutils.
  
• 　　The command unshare provides a new option --propagation=slave|shared|private|unchanged
  　　to control propagation in mount namespaces.
  　　
  
• 　　The command mount(8) supports read-only binds in one step by the options
  　　"bind,ro" (command line or fstab).
  　　
  
• 　　The commands fdisk and sfdisk can be compiled with GNU readline support to
  　　improve their line-editing functionality.
  
• 　　The library libsmartcols and the commands findmnt, losetup, lsblk, lslocks,
  　　sfdisk and lsipc provide output in JSON format.
  
• 　　The command mkfs (deprecated in favour of mkfs.) does not use hard-coded
  　　paths, but it follows $PATH.
  
• 　　The command script has been massively improved to be more robust and less
  　　complex.  Now all is implemented by one process which monitors the running
  　　session by poll(), signalfd(), etc.

  　　--force is specified.
  　　
  
• 
  　　The command agetty>　　is displayed.
  
• 　　util-linux now supports and enables colors by default. It is possible to change
  　　this behavior with --disable-colors-default to be more user-friendly to colorblind
  　　people.
  　　
  
• 　　The command cfdisk displays more information about the selected partition
  
  　　(partition UUID, filesystem>　　
  
• 　　The command fdisk provides a new command 'F' to print free, unpartitioned space
  　　(gaps) on the disk.
  　　
  
• 　　The command cal supports the new options --twelve and --months  to display
  　　the next twelve or  months.
  
• 　　The command rtcwake supports a new option --list-modes to list available modes,
  　　and a new option --date for human-readable times. rtcwake does not support
  　　RTC_ALM_READ and RTC_ALM_SET fallbacks any more.
  
• 　　The util-linux code is possible rebuild with --disable-assert now.
