Restarting systemd
'dnf update' (using the tracer plugin) often tells me to restart
certain services via systemctl, which is fine. However on occasion it
tells me to restart something manually. I can usually figure out how to
do this, but the one I can't figure out is systemd itself:
...
You should restart:
* These applications manually:
systemd
# systemctl daemon-reexec
# tracer
You should restart:
* These applications manually:
systemd
Sending HUP, TERM etc. to systemd doesn't make any difference.
Is there a way to do this without rebooting?
For extra credit, why is the output of tracer different when running
via sudo or su within a GUI, compared with running directly as root
logged into a text console? The above commands were run using the
latter. When using the former, tracer gave no output.
