Previously the NixOS-specific configuration for man-db was in the
package itself and /etc/man.conf was completely ignored.
This change moves it to /etc/man_db.conf, making declarative
configuration practical again.
It's now possible to generate the mandb caches for all packages
installed through NixOS `environment.systemPackages` at build-time.
The standard location for the stateful cache (/var/cache/man) is also
configured to allow users to run `mandb` manually if they wish.
Since generating the cache can be expensive the option is off by
default.
In /etc/sudoers, the last-matched rule will override all
previously-matched rules. Thus, make the default rule show up first (but
still allow some wiggle room for a user to `mkBefore` it), before any
user-defined rules.
Done by setting `autopilot.min_quorum = 3`.
Techncially, this would have been required to keep the test correct since
Consul's "autopilot" "Dead Server Cleanup" was enabled by default (I believe
that was in Consul 0.8). Practically, the issue only occurred with our NixOS
test with releases >= `1.7.0-beta2` (see #90613). The setting itself is
available since Consul 1.6.2.
However, this setting was not documented clearly enough for anybody to notice,
and only the upstream issue https://github.com/hashicorp/consul/issues/8118
I filed brought that to light.
As explained there, the test could also have been made pass by applying the
more correct rolling reboot procedure
-m.wait_until_succeeds("[ $(consul members | grep -o alive | wc -l) == 5 ]")
+m.wait_until_succeeds(
+ "[ $(consul operator raft list-peers | grep true | wc -l) == 3 ]"
+)
but we also intend to test that Consul can regain consensus even if
the quorum gets temporarily broken.
The systemd socket unit files now more precisely track the IPFS
configuration, by including any multaddr they can make a `ListenStream`
for. (The daemon doesn't currently support anything which would use
`ListDatagram`, so we don't need to worry about that.)
The tests use some of these features.
Specifying mailboxes as a list isn't a good approach since this makes it
impossible to override values. For backwards-compatibility, it's still
possible to declare a list of mailboxes, but a deprecation warning will
be shown.
We need to keep the passthru.filesInstalledToEtc and passthru.defaultBlacklistedPlugins in sync with the package contents so let's add a test to enforce that.
Since cd1dedac67 systemd-networkd has it's
netlink socket created via a systemd.socket unit. One might think that
this doesn't make much sense since networkd is just going to create it's
own socket on startup anyway. The difference here is that we have
configuration-time control over things like socket buffer sizes vs
compile-time constants.
For larger setups where networkd has to create a lot of (virtual)
devices the default buffer size of currently 128MB is not enough.
A good example is a machine with >100 virtual interfaces (e.g.,
wireguard tunnels, VLANs, …) that all have to be brought up during
startup. The receive buffer size will spike due to all the generated
message from the new interfaces. Eventually some of the message will be
dropped since there is not enough (permitted) buffer space available.
By having networkd start through / with a netlink socket created by
systemd we can configure the `ReceiveBufferSize` parameter in the socket
options without recompiling networkd.
Since the actual memory requirements depend on hardware, timing, exact
configurations etc. it isn't currently possible to infer a good default
from within the NixOS module system. Administrators are advised to
monitor the logs of systemd-networkd for `rtnl: kernel receive buffer
overrun` spam and increase the memory as required.
Note: Increasing the ReceiveBufferSize doesn't allocate any memory. It
just increases the upper bound on the kernel side. The memory allocation
depends on the amount of messages that are queued on the kernel side of
the netlink socket.
udev gained native support to handle FIDO security tokens, so we don't
need a module which only added the now obsolete udev rules.

Upstream has this alias too; so that dbus activation works.
What I don't fully understand is why this would ever be useful given
this unit is already started way in early boot; even before dbus is up.
But lets just keep behaviour similar to upstream and then ask these
questions to upstream.
With this systemd buffers netlink messages in early boot from the kernel
itself; and passes them on to networkd for processing once it's started.
Makes sure no routing messages are missed.
Also makes an alias so that dbus can activate this unit. Upstream has
this too.
This will make dbus socket activation for it work
When `systemd-resolved` is restarted; this would lead to unavailability
of DNS lookups. You're supposed to use DBUS socket activation to buffer
resolved requests; such that restarts happen without downtime
This makes it possible to only start IPFS when needed. So a user’s
IPFS daemon only starts when they actually use it.
A few important warnings though:
- This probably shouldn’t be mixed with services.ipfs.autoMount
since you want /ipfs and /ipns aren’t activated like this
- ipfs.socket assumes that you are using ports 5001 and 8080 for the
API and gateway respectively. We could do some parsing to figure
out what is in apiAddress and gatewayAddress, but that’s kind of
difficult given the nonstandard address format.
- Apparently? this doesn’t work with the --api commands used in the tests.
Of course you can always start automatically with startWhenNeeded =
false, or just running ‘systemctl start ipfs.service’.
Tested with the following test (modified from tests/ipfs.nix):
import ./make-test-python.nix ({ pkgs, ...} : {
name = "ipfs";
nodes.machine = { ... }: {
services.ipfs = {
enable = true;
startWhenNeeded = true;
};
};
testScript = ''
start_all()
machine.wait_until_succeeds("ipfs id")
ipfs_hash = machine.succeed("echo fnord | ipfs add | awk '{ print $2 }'")
machine.succeed(f"ipfs cat /ipfs/{ipfs_hash.strip()} | grep fnord")
'';
})

Update nixos/modules/services/network-filesystems/ipfs.nix

Previously we had three services for different config flavors. This is
confusing because only one instance of IPFS can run on a host / port
combination at once. So move all into ipfs.service, which contains the
configuration specified in services.ipfs.
Also remove the env wrapper and just use systemd env configuration.
This should have been done initially, as otherwise it gets awfully
awkward to boot into new generations by default.
This system-specific image wasn't expected to be long-lived, thus why it
didn't end up being polished much.
Reality shows us we may be stuck with it for a bit longer, so let's make
it easier to use for new users.
The way this ends up being called with the raspberry pi 4 image builder
ends up not using the `-e` from the shebang.
In turn, the builds fails during cross-compilation. The wrong coreutils
ends up being used, but this is not made apparent.
The issue I faced is already fixed on master, but this ensures no one
ends up with a failed build "succeeding".
The default `undervolt` package does not accept floating point numbers for any of its numeric
arguments. This also mentions in what units are the values expressed.
The setgid is currently required for offline enqueuing, and
unfortunately smtpctl is currently not split from sendmail so there's
little running around it.
The OC_PASS environment variable can be used to create a user with
`occ user:add --password-from-env`. It is currently not possible to
use the `nextcloud-occ` to "non-interactively" create a user since
this variable is ignored by sudo.
This switches the unit to Restart=on-failure and switches the CPU policy
to fifo (the daemon tries to do that itself, but is denied permission).
Also add the package to $PATH to be able to use fs_cli easily.
It's pbPort, and it's also a connection string, meaning
listen-on-localhost is also possible. Provide an alias for the old
option name, so old configs still work.
This patch was done by curro:
The generated /etc/pam.d/* service files invoke the pam_systemd.so
session module before pam_mount.so, if both are enabled (e.g. via
security.pam.services.foo.startSession and
security.pam.services.foo.pamMount respectively).
This doesn't work in the most common scenario where the user's home
directory is stored in a pam-mounted encrypted volume (because systemd
will fail to access the user's systemd configuration).
This fixes a regression from 993baa587c which requires
networking.hostName to be a valid DNS label [0].
Unfortunately we missed the fact that the hostnames may also be empty,
if the user wants to obtain it from a DHCP server. This is even required
by a few modules/images (e.g. Amazon EC2, Azure, and Google Compute).
