Custom command for containers not working

[troglobit]

Setting up a container with a custom command does not seem to be working properly:

admin@infix-00-00-00:/config/> edit container httpd
admin@infix-00-00-00:/config/container/httpd/> set image oci-archive:/lib/oci/curios-httpd-v24.03.0.tar.gz
admin@infix-00-00-00:/config/container/httpd/> set command "curios-httpd-v24.03.0 /usr/sbin/httpd -f -v -p 8080"                 -I/home/jocke/src/x-misc/output/build/edk2-edk2-stable202308/MdePkg/Test/UnitTest/Incutput/build/edk2-edk2-stable202308
admin@infix-00-00-00:/config/container/httpd/> set network host
admin@infix-00-00-00:/config/container/httpd/> set command "/usr/sbin/httpd -f -v -p 8080"
admin@infix-00-00-00:/config/container/httpd/> show
image oci-archive:/lib/oci/curios-httpd-v24.03.0.tar.gz;
command "/usr/sbin/httpd -f -v -p 8080";
network {
  host true;
}
admin@infix-00-00-00:/config/container/httpd/> leave
admin@infix-00-00-00:/> copy running-config startup-config 

The log shows:

Finit tries to restart it 10 times and then gives up.

Calling container -n httpd start (same as Finit) gives the following output:

admin@infix-00-00-00:~$ sudo container -n httpd start
Error: unable to start container "fac5da6019a24253aba41c93abf54478d482a5eb11132abb638e3cfd75f80c7e": crun: executable file `""` not found in $PATH: No such file or directory: OCI runtime attempted to invoke a command that was not found

Creating another container, using the same command, and manually starting it, works:

admin@infix-00-00-00:~$ sudo podman create --name foo --conmon-pidfile=/run/container:httpd.pid  --replace --quiet --cgroup-parent=containers  --restart=always --systemd=false --tz=local      --entrypoint=""   --log-driver k8s-file --log-opt path=/run/containers/httpd.fifo --net=host curios-httpd-v24.03.0 /usr/sbin/httpd -f -v -p 8080

admin@infix-00-00-00:~$ sudo podman start foo
foo
admin@infix-00-00-00:~$ sudo podman ps

Even connecting to httpd on port 8080 from the outside works:

$ curl http://192.168.122.161:8080/
