Hi, question that I don't understand,
I'd be grateful for explaining or reference to what I should read to get it.
Why during Podman build command
`systemctl enable httpd`
is working
but
`systemctl status httpd`
is not working?
Dockerfile not working:
```
FROM registry.access.redhat.com/ubi8/ubi-init
RUN yum -y install httpd; yum clean all;
RUN systemctl enable httpd;
RUN systemctl status httpd;
```
output of `podman build .`:
```
STEP 2/4: RUN yum -y install httpd; yum clean all;
STEP 1/4: FROM registry.access.redhat.com/ubi8/ubi-init
Build output:
--> 02f6efde590f
--> Using cache 02f6efde590f9fec989c04a01a661d2650b462aeb8e61ad3c0e00aae1b16b1ef

STEP 4/4: RUN systemctl status httpd;

System has not been booted with systemd as init system (PID 1). Can't operate.
Failed to connect to bus: Host is down
```
But!
If I exec into the container when he is running both of them are working.
Working Dockerfile:
```
FROM registry.access.redhat.com/ubi8/ubi-init
RUN yum -y install httpd; yum clean all;
RUN systemctl enable httpd;
```
command:
`podman build . -t x ; podman run -d --name x x ; podman exec -ti x bash -c
"systemctl status httpd"`
runs with success
```
