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.

Initially we planned to run jobs in those nodes by sharing the same nix
store from hut. However, these nodes are now used to build packages
which are not available in hut. Users also ssh to the nodes, which
doesn't mount the hut store, so it doesn't make much sense to keep
mounting it.

The current select mechanism was using the memory too as a consumable
resource, which by default only sets 1 MiB per node. As each job already
requests 1 MiB, it prevents other jobs from running.
As we are not really concerned with memory usage, we only use the unused
cores in the select criteria.

Starting with GitLab 16, there is a new mechanism to authenticate the
runners via authentication tokens, so use it instead. Older tokens and
runners are also removed, as they are no longer used.
With the new way of managing tokens, both the tags and the locked state
are managed from the GitLab web page.

To accomodate the raccoon knights workstation, some of the configuration

specific parts are placed into m/common/xeon.nix and only the common

option, but defines the list attribute `hosts` for each user, which
filters users so that only the user can only access those hosts.
