systemd 253.5-1ubuntu3 source package in Ubuntu

 This package contains a plugin for the Name Service Switch, providing host
 name resolution for the locally configured system hostname as returned by
 gethostname(2). It returns all locally configured public IP addresses or -- if
 none are configured, the IPv4 address 127.0.1.1 (which is on the local
 loopback) and the IPv6 address ::1 (which is the local host).
 .
 A lot of software relies on that the local host name is resolvable. This
 package provides an alternative to the fragile and error-prone manual editing
 of /etc/hosts.
 .
 Installing this package automatically adds myhostname to /etc/nsswitch.conf.

 nss-mymachines is a plugin for the GNU Name Service Switch (NSS) functionality
 of the GNU C Library (glibc) providing hostname resolution for local containers
 that are registered with systemd-machined.service(8). The container names are
 resolved to IP addresses of the specific container, ordered by their scope.
 .
 Installing this package automatically adds mymachines to /etc/nsswitch.conf.

 nss-resolve is a plugin for the GNU Name Service Switch (NSS) functionality
 of the GNU C Library (glibc) providing DNS and LLMNR resolution to programs via
 the systemd-resolved daemon (provided in the systemd-resolved package).
 .
 Installing this package automatically adds resolve to /etc/nsswitch.conf.

 nss-systemd is a plug-in module for the GNU Name Service Switch (NSS)
 functionality of the GNU C Library (glibc), providing UNIX user and group name
 resolution for dynamic users and groups allocated through the DynamicUser=
 option in systemd unit files. See systemd.exec(5) for details on this
 option.
 .
 Installing this package automatically adds the module to /etc/nsswitch.conf.

 This package contains the PAM module which registers user sessions in
 the systemd control group hierarchy for logind.
 .
 If in doubt, do install this package.
 .
 Packages that depend on logind functionality need to depend on libpam-systemd.

 This library provides APIs to interface with various system components such as
 the system journal, the system service manager, D-Bus and more.
 .
 This package contains the files needed for developing applications that
 use libsystemd.

 This internal shared library provides common code used by various systemd
 components. It is supposed to decrease memory and disk footprint.
 The shared library is not meant for public use and is not API or ABI stable.

 This library provides APIs to interface with various system components such as
 the system journal, the system service manager, D-Bus and more.

 This library provides APIs to introspect and enumerate devices on the local
 system.

 systemd is a system and service manager for Linux. It provides aggressive
 parallelization capabilities, uses socket and D-Bus activation for starting
 services, offers on-demand starting of daemons, keeps track of processes using
 Linux control groups, maintains mount and automount points and implements an
 elaborate transactional dependency-based service control logic.
 .
 Installing the systemd package will not switch your init system unless you
 boot with init=/lib/systemd/systemd or install systemd-sysv in addition.

 systemd-boot (short: sd-boot) is a simple UEFI boot manager. It provides a
 textual menu to select the entry to boot and an editor for the kernel command
 line. It supports systems with UEFI firmware only.
 .
 Installing systemd-boot will configure and install it in the ESP.
 .
 This package contains various tools and services to manage systems using
 systemd-boot.

 line. It supports systems with UEFI firmware only.
 .
 This package contains the EFI binaries.

 This package provides systemd's tools for nspawn and container/VM management:
  * systemd-nspawn
  * systemd-machined and machinectl
  * systemd-importd
  * systemd-portabled and portablectl

 This package provides systemd tools for storing and retrieving coredumps:
  * systemd-coredump
  * coredumpctl

 This package contains the systemd and udev pkg-config files. Note that these
 are different from the libsystemd's and libudev's pkg-config files, which can
 still be found in the respective dev packages, but instead provide data such as
 the installation directories for units, and more.

 systemd-homed is a system service designed to manage home directories. This
 package includes the homed service, a PAM module to automatically mount home
 directories on user login, tools and documentation.

 This package provides tools for sending and receiving remote journal logs:
  * systemd-journal-remote
  * systemd-journal-upload
  * systemd-journal-gatewayd

 systemd-oomd is a system service that uses cgroups-v2 and
 pressure stall information (PSI) to monitor and take action on
 processes before an OOM occurs in kernel space.

 This package provides systemd's DNS resolver and the command line tool to
 manage it.
 .
 Installing this package automatically overwrites /etc/resolv.conf and switches
 it to be managed by systemd-resolved.

 Standalone sysusers binary with minimal dependencies.
 This package conflicts with the main systemd package and is meant for use in
 non-systemd systems.

 Standalone tmpfiles binary with minimal dependencies.
 This package conflicts with the main systemd package and is meant for use in
 non-systemd systems.

 This package provides manual pages and compatibility symlinks needed for
 systemd to replace sysvinit.
 .
 Installing systemd-sysv will overwrite /sbin/init with a symlink to systemd.

 This package contains the test binaries. Those binaries are primarily used
 for autopkgtest and not meant to be installed on regular user systems.

 The package contains the systemd-timesyncd system service that may be used to
 synchronize the local system clock with a remote Network Time Protocol server.

 systemd-userdbd is a system service that multiplexes user/group lookups to all
 local services that provide JSON user/group record definitions to the system.
 In addition it synthesizes JSON user/group records from classic UNIX/glibc NSS
 user/group records in order to provide full backwards compatibility. It may
 also pick up statically defined JSON user/group records from drop-in files.

 udev is a daemon which dynamically creates and removes device nodes from
 /dev/, handles hotplug events and loads drivers at boot time.
