It's a very useful backend (that probably should be enabled by default,
like on Ubuntu), let's start by making it easier to discover.
Ref https://github.com/NixOS/nixpkgs/issues/28406.
Building etc."fish/setEnvironment.fish" needs
config.system.build.setEnvironment, which can be very large. And what
babelfishTranslate does is to translate env vars exported by bash
syntax, which does not need much computing power.
This patch can reduce the network traffic when using remote builders
with almost no harm.
Previously, dhcpcd and bitcoind starting up in parallel could lead to
the following error in bitcoind:
```
bitcoind: libevent: getaddrinfo: address family for nodename not supported
bitcoind: Binding RPC on address 127.0.0.1 port 8332 failed.
bitcoind: Unable to bind any endpoint for
```
After the initial failure, the bitcoind service would always restart successfully.
This race condition, where both applications were simultaneously
manipulating network resources, was only triggered under specific
hardware conditions.
Fix it by running bitcoind after dhcp has started (by running after
`network-online.target`).
This bug and the fix only affect the default NixOS scripted
networking backend.
The new defaults allows jenkins-job-builder to reload the configuration
out-of-the-box, whereas the previous defaults required users to manually
reload/restart jenkins, or configure accessUser/accessTokenFile
themselves.
(If `extraJavaOptions = [ "-Djenkins.install.runSetupWizard=false" ]`
then the initial admin user is *not* created and you have to use JCasC
or something else to bootstrap.)
Netdev collector needs AF_NETLINK permissions to work. It will fail with
the message "couldn't get netstats: socket: address family is not
supported by protocol" otherwise.
If folders and devices are not configured explicitly, do not wipe the
changes done via the web GUI. Currently the list of devices or folders
will be reset unless overrideFolders/overrideDevices is disabled.
