Pre-installing the package ifenslave seems to break the installer.
I’ve been working on a solution to preinstall some packages to make it possible to setup offline targets.
I’ve come up with a script that mounts casper/filesystem.squashfs, chroot-install some packages, configures my autoinstall script (nocloud) and repacking everything into a new filesystem.squashfs. It’s heavily inspired on inject-subiquity-snap.sh following mwhudson’s suggestions : Automated Server Install Quickstart.
But preinstalling ifenslave makes the installer to crash.

Check especially the “PARAMETERS” section before running it.
