RHBA-2018:2753 systemd bug fix update
Updated systemd packages that fix one bug are now available for Red Hat Enterprise Linux 7.
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 bug:
* Previously, the state of the automount unit in some cases did not follow changes of corresponding mount unit. During upgrade from Red Hat Enterprise Linux (RHEL) 7.3 to RHEL 7.5, the systemd manager was reexecuted, which stopped all mount units activated via automount. However, automount unit did not reflect that, therefore subsequent access notifications for the mount point were ignored, as if the mount point was already mounted. Any process that tried to access such a mount point then became unresponsive. With this update, the state of automount unit changes when the corresponding mount unit’s state changes. As a result, the described problem no longer occurs. (BZ#1608678)
Users of systemd are advised to upgrade to these updated packages, which fix this bug.
