- In particular, 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.

* Support for dynamically creating users for the lifetime of a service
has been added. If DynamicUser=yes is specified, user and group IDs
will be allocated from the range 61184..65519 for the lifetime of the
