[Nut-upsuser] Debian 13 (NUT 2.8.1) fixes upssched bug, but floods systemctl log

Well, as a sort of hot-fix, you could  edit
`/usr/lib/systemd/system/nut-monitor.service` to replace ExecStart from a
direct command call to a shell snippet, something like:

-ExecStart=/usr/local/ups/sbin/upsmon -F
+ExecStart=/bin/sh -c '/usr/local/ups/sbin/upsmon -F | grep -v "Network UPS
Tools upsmon 2.8.1"'

NOTE: If here you would be editing the file directly, it would be likely
overwritten by eventual package upgrade - but then it would hopefully be
with a more recent NUT.

Hm, or a minor packaging patch.

Then maybe a site-local "drop-in" override would be better:

:; mkdir -p /etc/systemd/system/nut-monitor.service.d
:; cat > /etc/systemd/system/nut-monitor.service.d/filter.conf << 'EOF'
[Service]
ExecStart=
ExecStart=/bin/sh -c '/usr/local/ups/sbin/upsmon -F | grep -vE "Network UPS
Tools .* 2\.8\.[012]"'
EOF
:; systemctl daemon-reload
:; systemctl restart nut-monitor

BEWARE: This is based on my local build that went into under
/usr/local/ups/ - the packaged path to upsmon in your case would likely
differ.

Hope this helps,
Jim Klimov
