Util-linux-ng 2.13 Release Notes
================================

Release highlights:
------------------

 mount(8) doesn't include NFS client code anymore. Don't forget to
 install nfs-utils 1.1.0 or newer with /sbin/[u]mount.{nfs,nfs4}.

 mount(8) doesn't include filesystem detection code anymore. You
 have to compile --with-fsprobe={blkid,volume_id}, and libblkid
 (e2fsprogs) or libvolume_id (udev >= v110) is required.

 mount(8) supports new relatime, context, fscontext, and defcontext
 mount options.

 losetup(8) supports command line option "-a" to list all used loop
 devices, '-s' to print a device name if "-f" and a file argument
 are present, and "-r" to create a read-only loop device.

 fdisk(8) Sun label support has been improved. fdisk(8) is also able
 to warn about detected GPT (fdisk doesn't support GPT).

 taskset(1) is independent on hardcoded NR_CPUS. chrt(1) supports
 SCHED_BATCH scheduling policy.

 The package build system is now based on autotools. The build system
 supports  separate CFLAGS and LDFLAGS for suid programs (SUID_CFLAGS,
 SUID_LDFLAGS). For more details see the README file

 hwclock(8) supports command line option --rtc=<path> and /dev/rtc0
 device. --systohc functionality has been improved, and it doesn't cause
 a 500ms inaccuracy each time it is used.

 Audit system support (--with-audit) has been added to hwclock(8) and
 login(1).

 SELinux support (--with-selinux) has been added to mkswap(8) and
 mount(8).

 The setarch(8) upstream has been merged with util-linux-ng.


Fixed security issues:
---------------------

 CVE-2007-0822 - mount(8) allows local users to trigger a NULL
                 dereference and an application crash
 CVE-2006-7108 - login(1) omits PAM account validation when auth is
                 skipped
