openSUSE MicroOS with the following modifications:
- systemd-boot instead of grub
- systemd-networkd and iwd instead of NetworkManager
- no ignition
- file triggers to use kernel-install for boot manager control
- single /var subvolme for all data directories

TODO:

- call kernel-install also in snapper plugin to avoid duplicating logic
- use systemd-bless-boot to rollback in case of faulty snapshot

Caveats:
- UEFI only
- no secure boot/key from home:lnussel. Use firmware without certs
