$SYSTEMD_NSPAWN_SHARE_NS_UTS may be used to control the unsharing of
individual namespaces.
+ * systemd-udevd.service is now run in a Seccomp-based sandbox that
+ prohibits access to AF_INET and AF_INET6 sockets and thus access to
+ the network. This might break code that runs from udev rules that
+ tries to talk to the network. Doing that is generally a bad idea and
+ unsafe due to a variety of reasons. It's also racy as device
+ management would race against network configuration. It is
+ recommended to rework such rules to use the SYSTEMD_WANTS property on
+ the relevant devices to pull in a proper systemd service (which can
+ be sandboxed differently and ordered correctly after the network
+ having come up). If that's not possible consider reverting this
+ sandboxing feature locally by removing the RestrictAddressFamilies=
+ setting from the systemd-udevd.service unit file, or adding AF_INET
+ and AF_INET6 to it.
