NAME

       needs-restarting - redirecting to DNF needs-restarting Plugin

       Check for running processes that should be restarted.

SYNOPSIS

       dnf needs-restarting [-u] [-r] [-s]

DESCRIPTION

       needs-restarting  looks  through running processes and tries to detect those that use files from packages
       that have been updated after the given process started. Such processes are reported by this tool.

       Note that in most cases a process should survive update of its binary and libraries it is  using  without
       requiring  to  be  restarted  for  proper  operation. There are however specific cases when this does not
       apply. Separately, processes often need to be restarted to reflect security updates.

       NOTE:
          Needs-restarting will try to guess the boot time using two different methods:

          st_mtime of /proc/1
                 Reflects the time the first process was run after booting.  This  works  for  all  known  cases
                 except machines without a RTC—they awake at the start of the epoch.

          /proc/uptime
                 Seconds field of /proc/uptime subtracted from the current time.  Works for machines without RTC
                 if  the  current  time  is  reasonably  correct.  Does not work on containers which share their
                 kernel with the host—there, the host kernel uptime is returned.

       WARNING:
          Some systems are configured to read the RTC time in the local time zone. This  mode  cannot  be  fully
          supported.  It  will  create  various  problems  with  time  zone  changes  and  daylight  saving time
          adjustments. The RTC time is never updated, it relies on external facilities to maintain it. If at all
          possible, use RTC in UTC by calling  timedatectl  set-local-rtc  0.   See  man  timedatectl  for  more
          information.

OPTIONS

       All general DNF options are accepted, see Options in dnf(8) for details.

       -u, --useronly
              Only consider processes belonging to the running user.

       -r, --reboothint
              Only report whether a reboot is required (exit code 1) or not (exit code 0).

       -s, --services
              Only list the affected systemd services.

       --exclude-services
              Don’t list stale processes that correspond to a systemd service.

CONFIGURATION

       /etc/dnf/plugins/needs-restarting.d/

       /etc/dnf/plugins/needs-restarting.d/pkgname.conf

       Packages  can  be added to needs-restarting via conf files in config directory. Config files need to have
       .conf extension or will be ignored.

       More than one package is allowed in each file (one package per line) although it is advised  to  use  one
       file for each package.

       Example:

          echo "dwm" > /etc/dnf/plugins/needs-restarting.d/dwm.conf
