Manual fan mode pins the fans at a fixed duty and never ramps, so a sustained
load had no cooling response until the BMC's own critical-temperature
override stepped in. docker-idrac.sh solved that, but needs Docker, which is
not installed on the host.
ipmi-fancontrol-daemon polls the CPU sensors and switches between the fixed
duty and the BMC's automatic curve around a threshold, which is what that
container did. Measured on the host: 1440 RPM pinned versus roughly 4200 RPM
on the automatic curve at the same 60C.
- Hysteresis, default 5C, stops the fans oscillating at the boundary.
- An unreadable temperature fails safe to automatic rather than staying
pinned.
- SIGTERM restores the automatic curve, with ExecStopPost as the backstop for
an outright kill.
Default to the local "open" interface. It needs no credentials and no
network, which matters for the shutdown path, where lanplus to the iDRAC
could fail once networking is down. ipmi-fancontrol-auto and -manual honour
the same setting and stay available for ad-hoc use.
Enable the third-party PCIe cooling response suppression that docker-idrac.sh
was configured with, so the automatic curve is not held to a raised floor by
the aftermarket NICs.

Checked against the live host. None of these are in service:
- sriov-enp4s0.service and set-ixgbe-vfmacs-enp4s0.sh target enp4s0f1np1,
which no longer exists; sriov_numvfs is 0 on every port and the unit was
never installed.
- nic-performance-tweaks.service was never installed either, though its
interfaces do still exist, so it would work if reinstated.
- vm-watchdog.sh watches VMID 2801 "pfsense", which no longer exists.
- lxc-watchdog.sh still carries the upstream example targets: CT 100 and
CT 101 on 192.168.31.0/24, a subnet that is not in use.
Neither watchdog is scheduled; there is no root crontab.
The watchdog config moves to unused/conf/ alongside them, so the scripts
resolve it unchanged from their new location.

stop-pa-vm.service calls the PAN-OS XML API on host shutdown so the firewall
VM goes down cleanly rather than being killed.
The API key is read from conf/pa-vm.conf, resolved relative to the script.
See conf/pa-vm.conf.example.
Pass the request through curl --config on stdin with the key in an X-PAN-KEY
header, instead of embedding it in the URL. A key in the query string is
visible in ps and would be recorded in any proxy or webserver log along the
path.

ipmi-fancontrol.service pins the fans to a fixed speed on start and hands
control back to the BMC's automatic curve on stop, to quiet the chassis.
BMC credentials are read from conf/ipmi-fancontrol.conf, resolved relative
to the scripts themselves so the tree stays self-contained whether it is run
from a checkout or from /opt/ergosteur. See conf/ipmi-fancontrol.conf.example.
Use ipmitool -E rather than -P so the password is passed via the environment
instead of argv, where any local user could read it out of ps.
docker-idrac.sh is the alternative temperature-aware controller.

sriov-enp4s0.service allocates VFs on the ixgbe ports at boot and applies
persistent VF MACs via set-ixgbe-vfmacs-enp4s0.sh, so guests keep stable
addresses across host reboots. The VF MAC assignments are currently all
commented out.
nic-performance-tweaks.service raises ring buffers and txqueuelen on the
uplinks and vmbr0.
unused/ holds the equivalent pair for the retired enp130s0 adapter.
