podman-systemd [Build] Volume= documentation bug

[Domini]

Issue Description

Manual says

Mount a volume to containers when executing RUN instructions during the build. This is equivalent to the --volume option of podman build, and generally has the form [[SOURCE-VOLUME|HOST-DIR:]CONTAINER-DIR[:OPTIONS]].

If SOURCE-VOLUME starts with ., Quadlet resolves the path relative to the location of the unit file.

Special case:

If SOURCE-VOLUME ends with .volume, Quadlet will look for the corresponding .volume Quadlet unit. If found, Quadlet will use the name of the Volume set in the Unit, otherwise, systemd-$name is used. The generated systemd service contains a dependency on the service unit generated for that .volume unit, or on $name-volume.service if the .volume unit is not found. Note: the corresponding .volume file must exist.

However, podman-build manual says (and in reality this is how it works) that only HOST-DIR is supported, not referencing a SOURCE-VOLUME.

Steps to reproduce the issue

Steps to reproduce the issue

1. podman create volume test
2. Reference volume test in build ([Build] Volume=test:/test)

Describe the results you received

systemctl start of the build unit fails

Describe the results you expected

Docs should not describe referencing SOURCE-VOLUME
