RHBA-2020:2540 - Bug Fix Advisory

Topic

An update for systemd is now available for Red Hat Enterprise Linux 7.7
Extended Update Support.

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.

Bug Fix(es) and Enhancement(s):

• [FJ7.7 Bug]: systemd: system shutdown gets hang for 30 minutes when some

swap unit fails to stop (BZ#1825804)

• systemd segfaults reloading while serializing a service executing a

ExecStartPost command [rhel-7.7] (BZ#1837972)

• ExecStopPost not run after exit-failure for forking type (BZ#1840627)

Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied.
