Package systemd-udev
Rule-based device node and kernel event manager
This package contains systemd-udev and the rules and hardware database needed to
manage device nodes. This package is necessary on physical machines and in
virtual machines, but not in containers.
This package also provides systemd-timesyncd, a network time protocol daemon.
It also contains tools to manage encrypted home areas and secrets bound to the
machine, and to create or grow partitions and make file systems automatically.
Version: 256.7
See also: systemd, systemd-boot-unsigned, systemd-bootchart, systemd-container, systemd-devel, systemd-journal-remote, systemd-networkd, systemd-pam, systemd-resolved, systemd-swap, systemd-ukify.
