RHBA-2019:2356 - Bug Fix Advisory

Topic

Updated systemd packages that fix several bugs are now available for Red Hat Enterprise Linux 7.

Description

The systemd packages contain systemd, a system and service manager for Linux, compatible with the SysV and LSB init scripts. It provides aggressive parallelism capabilities, uses socket and D-Bus activation for starting services, offers on-demand starting of daemons, and keeps track of processes using Linux cgroups. In addition, it supports snapshotting and restoring of the system state, maintains mount and automount points, and implements an elaborate transactional dependency-based service control logic. It can also work as a drop-in replacement for sysvinit.

This update fixes the following bugs:

• keepalived will not terminate with systemctl stop (BZ#1729226)
• Layered slices are left in a "dead" state if slices are stopped that have child slices underneath (BZ#1729228)
• systemd respawns forever services triggered by a timer if fork() fails when executing ExecStart command (BZ#1729230)
• systemd.automount fails after update to 7.5 in case of missing mount point (BZ#1729231)
• systemd: Permission denied while opening PID file or unsafe symlink chain: /var/run/chrony/chronyd.pid (#1729414)

Users of systemd are advised to upgrade to these updated packages, which fix these bugs.
