for those interested to try it, I've created a COPR project and it is
possible to install bwrap-oci from there (ocitools is already available
for F24):

$ sudo dnf copr enable -y gscrivano/bwrap-oci
$ sudo dnf install -y ocitools bwrap-oci

### Create a rootfs and install emacs there
$ mkdir -p emacs/rootfs; cd emacs
$ sudo dnf install -y --releasever=24 --installroot=$(pwd)/rootfs emacs

### Generate the OCI configuration file
$ ocitools generate --tty --args /usr/bin/emacs > config.json

### Run bwrap-oci, which reads the config.json file generated by ocitools
### and executes bubblewrap
$ bwrap-oci
