Util-linux 2.36 Release Notes
=============================
Release highlights
------------------
irqtop(1) and lsirq(1) are NEW COMMANDS to monitor kernel interrupts.
cal(1) provides a new --vertical command line option to output calendar
in vertical mode.
blkzone(8) implements open/close/finish commands now.
unshare(1) and nsenter(1) commands support the time namespace now.
agetty(8) now supports multiple paths in the option --issue-file.
The commands fdisk(8), sfdisk(8), cfdisk(8), mkswap(8) and wipefs(8) now
support block devices locking by flock(2) to better behave with udevd or other
tools. Ffor more details see https://systemd.io/BLOCK_DEVICE_LOCKING/. This
feature is controlled by a new command line option --lock and
$LOCK_BLOCK_DEVICE environmental variable.
dmesg(1) supports a new command line option --follow-new to wait and print only
new kernel messages.
fdisk(8) provides a new command line option --list-details to print more
information about partition table. Another new command line option is
--noauto-pt. It's usable to don't automatically create default partition table
on empty devices.
The command fdisk(8) and sfdisk(8) support user-friendly aliases for partition
types. For example "echo 'size=10M type=uefi' | sfdisk /dev/sda" creates EFI
system partition on sda.
fstrim(8) supports new command line option --listed-in to specify alternatives
where to read list of the filesystems. This option makes fstrim systemd service
file more portable between distributions.
libfdisk provides API to relocate GPT backup header. This feature is usable to
generate small, but still valid images for containers and resize the image later.
This new feature is exported to command line by "sfdisk --relocate".
mount(8) now supports mount by ID= tag. The tag is a block device identifier as
used by udevd in /dev/disk/by-id. It's usually WWN or another HW related
identifier. This feature is designed for users who need to avoid filesystem or
partition table dependence in fstab. The udevd is required for this tag.
login(1) supports list of "message of the day" files and directories in the
option MOTD_FILE= in /etc/login.defs now. The default value is
/usr/share/misc/motd:/run/motd:/etc/motd.
All tools which read /etc/login.defs is possible to compile with libeconf now.
The build system provides a new option --disable-hwclock-gplv3 to avoid optional
GPLv3 code in the command hwclock(8).
more(1) has been refactored to meet 21st century codding standards. Thanks to
Sami Kerola.
Thanks to Michael Kerrisk for massive man pages cleanup.
