Package: nbdkit Version: 1.14.2-2 I noticed that nbdkit failed to build on raspbian because the iso plugin had not been built, further investigation indicated this was because genisoimage was not installed.
It seems that on Debian this gets pulled in indirectly, while on raspbian it doesn't, i'm not really sure why, but given that your package directly tests for genisoimage and fails to build if it doesn't find it, it should really have a build-dependency on it even if things happen to work on Debian at the moment. I also noticed that if cargo is installed during the build then nbdkit tried and failed to build a rust plugin, you might want to consider adding a build-conflicts or possiblly adding some kind of configure parameter to prevent this.
