In all machines, as soon as we recover the power, turn the machine back
on. We cannot rely on the previous state as we will shut them down
before the power is cut to prevent damage on the power supply
monitoring circuit.

Access internal hosts via apex proxy. From the compute nodes we first
open an SSH connection to apex, and then tunnel it through the HTTP
proxy with netcat.
This way we allow reaching internal GitLab repositories without
requiring the user to have credentials in the remote host, while we can
use multiple remotes to provide redundancy.

The fox machine will be placed in the UPC network, so we update the
configuration with the new IP and gateway. We won't be able to reach hut
directly so we also remove the host entry and proxy.

From the documentation of keep-outputs, setting it to true would prevent
the GC from removing build time dependencies:
If true, the garbage collector will keep the outputs of non-garbage
derivations. If false (default), outputs will be deleted unless they are
GC roots themselves (or reachable from other roots).
In general, outputs must be registered as roots separately. However,
even if the output of a derivation is registered as a root, the
collector will still delete store paths that are used only at build time
(e.g., the C compiler, or source tarballs downloaded from the network).
To prevent it from doing so, set this option to true.

For owl1 and owl2 directly connect to hut via LAN with HTTP, but for

Apparently the ttyS0 console doesn't exist but ttyS1 does:
raccoon% sudo stty -F /dev/ttyS0
stty: /dev/ttyS0: Input/output error
raccoon% sudo stty -F /dev/ttyS1
speed 9600 baud; line = 0;
-brkint -imaxbel
The dmesg line agrees:
00:03: ttyS1 at I/O 0x2f8 (irq = 3, base_baud = 115200) is a 16550A
The console configuration is then moved from base to xeon to allow
changing it for the raccoon machine.
