v0.0.7 and v0.0.8 is broken:
$ docker run --rm --volume "$(pwd):/data" --user $(id -u):$(id -g) deserializeme/pxeless:v0.0.7 -a -u user-data.basic -n jammy -r
Digest: sha256:7a1862ac4d38c493a9cebed3dc31a57f7cf1e843bdd0a04e42ad05b09f193826

v0.0.6 is works:
$ docker run --rm --volume "$(pwd):/data" --user $(id -u):$(id -g) deserializeme/pxeless:v0.0.6 -a -u user-data.basic -n jammy -r

I assume this issue has been missed as it (probably) works if you have image-create.sh in $(pwd)
