Util-linux-ng 2.18 Release Notes
================================

The util-linux-ng package does not contain rdev(8), ramsize(8), 
vidmode(8) and rootflags(8) anymore. 

The fdisk(8) command does not use DOS-compatible mode and cylinders as display
units by default. The old deprecated DOS behavior could be enabled by 'c' and
'u' fdisk commands or from command line by '-c=dos -u=cylinders' options.

Release highlights
------------------

libmount:
  - this NEW LIBRARY is designed to be used in low-level utils like
    mount(8) and /sbin/mount.<type> helpers as well as in some other
    projects.

  - the library API is still officially unstable. The library provides
    fstab, mtab and mountinfo parser, routines for work with parsed 
    data and mount options, mtab locking, etc. The high-level API for 
    mount(2) is planned for the next major release. For more details see:
    http://thread.gmane.org/gmane.linux.utilities.util-linux-ng/3239

  - the utils like mount(8) or umount(8) are not linked with the library
    yet. This change is planned for util-linux-ng-2.19.

findmnt(8):
  - this NEW COMMAND is a command line interface to the libmount library 
    for work with mountinfo, fstab and mtab files

fsfreeze(8):
   - this NEW COMMAND is very simple wrapper around FIFREEZE/FITHAW ioctls

swaplabel(8):
   - this NEW COMMAND allows to change swaparea UUID and label

blkid(8):
  - supports new command line option "-i" to print I/O Limits

  - supports new command line option "-n" to restrict probing functions to 
    defined list of superblock types (names).

  - returns details from partition table (type, flags, uuid, ...)

chrt(1):
  - supports new command line option "-R/--reset-on-fork" to enable 
    SCHED_RESET_ON_FORK flag

fdisk(8):
  - supports new command line option "-c" to switch off DOS mode
  - uses 1MiB offset for the first partition
    (all these changes are already in the release 2.17.2)

hwclock(8):
  - supports new command line option "--predict" to predict what the RTC will 
    read at time given by the --date option based on the adjtime file.

ldattach(8):
  - supports new command line option "-i/--iflag" to sets the specified bits 
    in the c_iflag word of the serial line.

fallocate(1), losetup(8) and mount(8):
  - the options --offset, --length or --sizelimit support suffixes
    (MiB, GiB, ...) and hex numbers

umount(8):
  - supports new command line option "--fake" to avoid umount(2) syscall
