| ### Bug fixes and enhancements | ||
|
|
||
| - Fixed an issue that could persistently prevent daemon startup after failure to initialize the default bridge. [moby/moby#49307](https://github.com/moby/moby/pull/49307) | ||
| - On a host that cannot load the `br_netfilter` module when it's needed, set environment variable `DOCKER_IGNORE_BR_NETFILTER_ERROR=1` to ignore the problem. Some things won't work! Including disabling inter-container communication in a bridge network and, with the userland proxy disabled, it won't be possible to access one container's published ports from another container on the same network.

Looks like vale doesn't like the exclamation mark (!) here

Perhaps we could change this to be more active voiced, and something like "Add a DOCKER_IGNORE_BR_NETFILTER_ERROR=1 to allow running on hosts that cannot load br_netfilter", but keeping some warning after that to make sure it's clear that it's not a good setup.

Sounds good ... I think they were my words from the PR, and my voice is generally about as active as the rest of me!

Oh, sorry @vvoland ... I think we need to keep the warning. This escape hatch is quite dangerous!
