image/prepare: Check if container is actually ubuntu (#636)

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

 | A **correct** init process | _Main article: [Docker and the PID 1 zombie reaping problem](http://blog.phusion.nl/2015/01/20/docker-and-the-pid-1-zombie-reaping-problem/)._ <br><br>According to the Unix process model, [the init process](https://en.wikipedia.org/wiki/Init) -- PID 1 -- inherits all [orphaned child processes](https://en.wikipedia.org/wiki/Orphan_process) and must [reap them](https://en.wikipedia.org/wiki/Wait_(system_call)). 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.**

+Here's an example showing you how a `runit` service directory can be

-    # 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 `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
+```Dockerfile
-    COPY memcached.sh /etc/service/memcached/run
+RUN mkdir /etc/service/memcached
-    RUN chmod +x /etc/service/memcached/run
+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.
+```
+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.

 | syslog-ng | 对于很多服务－包括kernel自身，都需要一个syslog后台进程，以便可以正确的将log输出到/var/log/syslog中。如果没有运行syslog后台进程，很多重要的信息就会默默的丢失了。<br/><br/>只对本地进行监听。所有syslog信息会被转发给“docker logs”。 |
