Prevent 'invalid escape sequence' errors in newer Python versions (#637)

The docker image `ubuntu:22.04` is not available for `riscv64`, which limits options for providing support for it here.

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project team at Phusion Passenger:
+
+[FloorD](https://github.com/floord) (she/her), floor@phusion.nl, English / Dutch / German
+
+[Scarhand](https://github.com/scarhand) (he/his), niels@phusion.nl, English / Dutch
+
+The project team will review and investigate all complaints, and will respond in a way that it deems appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4, available at [http://contributor-covenant.org/version/1/4][version]

Most Docker containers do not have an init process that does this correctly. As a result, their containers become filled with [zombie processes](https://en.wikipedia.org/wiki/Zombie_process) over time. <br><br>Furthermore, `docker stop` sends SIGTERM to the init process, which stops all services. Unfortunately most init systems don't do this correctly within Docker since they're built for hardware shutdowns instead. This causes processes to be hard killed with SIGKILL, which doesn't give them a chance to correctly deinitialize things. This can cause file corruption. <br><br>Baseimage-docker comes with an init process `/sbin/my_init` that performs both of these tasks correctly. |

 ### Adding additional daemons
 
-You can add additional daemons (e.g. your own app) to the image by creating runit entries. You only have to write a small shell script which runs your daemon, and runit will keep it up and running for you, restarting it when it crashes, etc.
+A daemon is a program which runs in the background of its system, such
+as a web server.
 
-The shell script must be called `run`, must be executable, and is to be placed in the directory `/etc/service/<NAME>`.
+You can add additional daemons (for example, your own app) to the image
+by creating runit service directories. You only have to write a small
+shell script which runs your daemon;
+[`runsv`](http://smarden.org/runit/runsv.8.html) will start your script,
+and - by default - restart it upon its exit, after waiting one second.
 
-Here's an example showing you how a memcached server runit entry can be made.
+The shell script must be called `run`, must be executable, and is to be
+placed in the directory `/etc/service/<NAME>`. `runsv` will switch to
+the directory and invoke `./run` after your container starts.
 
-In `memcached.sh` (make sure this file is chmod +x):
+**Be certain that you do not start your container using interactive mode
+(`-it`) with another command, as `runit` must be the first process to run. If you do this, your runit service directories won't be started. For instance, `docker run -it <name> bash` will bring you to bash in your container, but you'll lose all your daemons.**
 
-    #!/bin/sh
-    # `/sbin/setuser memcache` runs the given command as the user `memcache`.
-    # If you omit that part, the command will be run as root.
-    exec /sbin/setuser memcache /usr/bin/memcached >>/var/log/memcached.log 2>&1
+Here's an example showing you how a `runit` service directory can be
+made for a `memcached` server.
 
-In `Dockerfile`:
+In `memcached.sh`, or whatever you choose to name your file (make sure
+this file is chmod +x):
+```bash
+#!/bin/sh
+# `/sbin/setuser memcache` runs the given command as the user `memcache`.
+# If you omit that part, the command will be run as root.
+exec /sbin/setuser memcache /usr/bin/memcached >>/var/log/memcached.log 2>&1
+```
+In an accompanying `Dockerfile`:
 
-    RUN mkdir /etc/service/memcached
-    COPY memcached.sh /etc/service/memcached/run
-    RUN chmod +x /etc/service/memcached/run
-
-Note that the shell script must run the daemon **without letting it daemonize/fork it**. Usually, daemons provide a command line flag or a config file option for that.
+```Dockerfile
+RUN mkdir /etc/service/memcached
+COPY memcached.sh /etc/service/memcached/run
+RUN chmod +x /etc/service/memcached/run
+```
+A given shell script must run **without daemonizing or forking itself**;
+this is because `runit` will start and restart your script on its own.
+Usually, daemons provide a command line flag or a config file option for
+preventing such behavior - essentially, you just want your script to run
+in the foreground, not the background.

+Baseimage-docker uses syslog-ng to provide a syslog facility to the container. Syslog-ng is not managed as an runit service (see below). Syslog messages are forwarded to the console.
+
+#### Log startup/shutdown sequence
+In order to ensure that all application log messages are captured by syslog-ng, syslog-ng is started separately before the runit supervisor process, and shutdown after runit exits. This uses the [startup script facility](#running_startup_scripts) provided by this image. This avoids a race condition which would exist if syslog-ng were managed as an runit service, where runit kills syslog-ng in parallel with the container's other services, causing log messages to be dropped during a graceful shutdown if syslog-ng exits while logs are still being produced by other services.

+In case you don't need one or more of these services in your image, you can disable its installation through the `image/buildconfig` that is sourced within `image/system_services.sh`.  Do this at build time by passing a variable in with `--build-arg`  as in `docker build --build-arg DISABLE_SYSLOG=1 image/`, or you may set the variable in `image/Dockerfile` with an ENV setting above the RUN directive.
 
-As shown in the following example, to prevent `sshd` from being installed into your image, set `1` to the `DISABLE_SSH` variable in the `./image/buildconfig` file.
