Binary packages built by this source

libnss-myhostname: nss module providing fallback resolution for the current hostname

 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.

libnss-myhostname-dbgsym: debug symbols for libnss-myhostname
libnss-mymachines: nss module to resolve hostnames for local container instances

 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.

libnss-resolve: nss module to resolve names via systemd-resolved

 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 package).
 .
 Installing this package automatically adds resolve to /etc/nsswitch.conf.

libnss-resolve-dbgsym: debug symbols for libnss-resolve
libnss-systemd: nss module providing dynamic user and group name resolution

 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.

libnss-systemd-dbgsym: debug symbols for libnss-systemd
libpam-systemd: system and service manager - PAM module

 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.

libsystemd-dev: systemd utility library - development files

 The libsystemd0 library provides interfaces to various systemd components.
 .
 This package contains the development files.

libudev-dev: libudev development files

 This package contains the files needed for developing applications that
 use libudev.

libudev1: libudev shared library

 This library provides access to udev device information.

libudev1-dbgsym: debug symbols for libudev1
libudev1-udeb: libudev shared library

 This library provides access to udev device information.
 .
 This is a minimal version, only for use in the installation system.

systemd: system and service manager

 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.
 .
 systemd is compatible with SysV and LSB init scripts and can work as a
 drop-in replacement for sysvinit.
 .
 Installing the systemd package will not switch your init system unless you
 boot with init=/bin/systemd or install systemd-sysv in addition.

systemd-container: systemd container/nspawn tools

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

systemd-container-dbgsym: debug symbols for systemd-container
systemd-coredump: tools for storing and retrieving coredumps

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

systemd-coredump-dbgsym: debug symbols for systemd-coredump
systemd-dbgsym: debug symbols for systemd
systemd-journal-remote: tools for sending and receiving remote journal logs

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

systemd-journal-remote-dbgsym: debug symbols for systemd-journal-remote
systemd-sysv: system and service manager - SysV links

 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.
 .
 systemd is compatible with SysV and LSB init scripts and can work as a
 drop-in replacement for sysvinit.
 .
 This package provides the manual pages and links needed for systemd
 to replace sysvinit. Installing systemd-sysv will overwrite /sbin/init with a
 link to systemd.

systemd-tests: tests for systemd

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

systemd-tests-dbgsym: debug symbols for systemd-tests
udev: /dev/ and hotplug management daemon

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