Util-linux 2.34 Release Notes
=============================

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

hardlink -- NEW COMMAND to consolidate duplicate files via hardlinks has been
merged into util-linux. The new command is not enabled by default. The original
author is Jakub Jelinek.

The command lsblk(8) has been rewritten. Now it keeps all hierarchy of the block
devices in memory before it's printed. It allows to modify or reorder the graph.
The new features based on this functionality are:

 * output de-duplication by --dedup, for example 'lsblk --dedup WWN' to
   de-duplicate devices by WWN number (e.g. multi-path devices)

 * merge repeating parts of the tree by --merge, see for example:
   http://karelzak.blogspot.com/2018/11/lsblk-merge.html

The command umount(8) now supports user unmount for FUSE mounts. The requirement
is FUSE specific user_id=<uid> in /proc/self/mountinfo for the filesystem. 

The command mount(8) now allows to use "--all -o remount". In this case all
filters (-t and -O) are applied to the table of already mounted filesystems.

The command su(1) now prefers /etc/default/su over /etc/login.defs and
ENV_SUPATH over ENV_ROOTPATH. The option --pty has been improved and it is not
marked as experimental anymore.

The command unshare(1) now allows set user ID and group ID by new command line
options -S/--setuid and -G/--setgid; and new options -R/--root and -w/--wd
allows to set root and working directory (like nsenter(1)).

The command lscpu(1) now prints 'Frequency boost' and 'Vulnerability' fields.
The caches calculation has been modified to print summary from all system caches
rather than per code numbers.

The command logger(1) merges multiple MESSAGE= lines into one journald message.

The library libblkid now does not depend on libuuid and newly supports DRBD9
detection.

The libsmartcols has been extended to support N:M relationships when print
tree-like output. This new feature is used by new lsblk --merge output.

The systemd services for fstrim and uuidd now contains hardening settings to
improve security and service isolation.

The command fstrim now trims also root filesystem on --fstab and checks for 
read-only filesystems on --all and --fstab. 

The package build-system now accepts --enable-asan to compile commands and
execute regression tests with addresses sanitizer.
