This allows us to continue to have the automatically sized image attempt
to build on Hydra, which should give us a good indication of when we've
got this fixed.
For reasons we haven't been able to work out, the aarch64 EC2 image now
regularly exceeds the output image size on hydra.nixos.org. As a
workaround, set this back to being statically sized again.
The other images do seem to build - it's just a case of the EC2 image
now being too large (occasionally non-determinstically).
This is supeer useful to allow the normal sd-image code to be used by
someone who wants to setup multiple partitions with a sd-image.
Currently I'm manually copying the sd-image file and modifying it
instead.
This is what is still exposed, and it allows me to control my lamps from
within home-assistant.
✗ PrivateNetwork= Service has access to the host's network 0.5
✗ RestrictAddressFamilies=~AF_(INET|INET6) Service may allocate Internet sockets 0.3

→ Overall exposure level for zigbee2mqtt.service: 1.3 OK 🙂
- Set an explicit umask that allows u+rwx and g+r.
- Adds `ProtectControlGroups` and `ProtectKernelLogs`, there should be
no need to access either.
- Adds `ProtectClock` to prevent write-access to the system clock.
- `ProtectProc` hides processes from other users within the /proc
filesystem and `ProcSubSet` hides all files/directories unrelated to
the process management of the units process.
- Sets `RemoveIPC`, as there is no SysV or POSIX IPC within nginx that I
know of.
- Restricts the creation of arbitrary namespaces
- Adds a reasonable `SystemCallFilter` preventing calls to @privileged,
@obsolete and others.
And finally applies some sorting based on the order these options appear
in systemd.exec(5).
See #119615 for more details. The aarch64-linux test failed with
"qemu-system-aarch64: Virtio VGA not available" so I've restricted the
test to x86_64-linux (the virtio paravirtualized 3D graphics driver is
likely only available on very few platforms).
The result still looks far from ideal but at least it gets recognized
now. "-fa Monospace" is required to switch to a font from the FreeType
library so that "-fs 24" works.
Note: Using linuxPackages_latest is not required anymore.
On reboots and shutdowns promtail blocks for at least 90 seconds,
because it would still try to deliver log messages for loki, which isn't
possible when the network has already gone down.
Upstreams example unit also uses a ten seconds timeout, something which
has worked pretty well for me as well.
systemd-nspawn can react to SIGTERM and send a shutdown signal to the container
init process. use that instead of going through dbus and machined to request
nspawn sending the signal, since during host shutdown machined or dbus may have
gone away by the point a container unit is stopped.
to solve the issue that a container that is still starting cannot be stopped
cleanly we must also handle this signal in containerInit/stage-2.
This reverts commit d6e0d38b84.
We need shorter secrets to continue working, since the earlier
recommendation was too short and there's no way to rotate the them.
The upstream recommended minimum length for db_key_base is 30 bytes,
which our option descriptions repeated. Recently, however, upstream
has, in many places, moved to using aes-256-gcm, which requires a key
of exactly 32 bytes. To allow for shorter keys, the upstream code pads
the key in some places. However, in many others, it just truncates the
key if it's too long, leaving it too short if it was to begin
with. This adds a patch that fixes this and updates the descriptions
to recommend a key of at least 32 characters.
