Turns out, #75510 was too restrictive.
We also need to allow str here, as some modules set this to
"/run/wrappers" to bring `/run/wrappers/bin` into $PATH of a unit.
Since Buildbot 0.9.0, status targets were deprecated and ignored.
There's a very small line on startup explaining that, and status simply
isn't reported. Avoid others the same headaches, and do it right in the
NixOS module.
As there might have been changes in the way reporters are organized, and
configuration might need to be migrated remove the old option, and not
just provide an alias.
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.
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.
