Usage example with /dev/vda being an extra mounted disk:

$ podman run --privileged --pid=host --net=none --security-opt label=type:unconfined_t quay.io/cgwalters/c9s-oscore:latest bootc install /dev/vda

Code and high level design

This merges a lot of code and logic from coreos-installer, coreos-assembler and some bits of fedora-coreos-config.

Unlike ostree, bootc install understands and manipulates block devices and bootloaders.

  • coreos-installer: ignition and blockdev.rs code
  • coreos-assember: sgdisk invocations and ostree repo setup translated to Rust
  • fedora-coreos-config: Things like transposefs, boot/root uuid handling are now done on the "install boot" here

Note this obviates much of the need for generating disk images. That said, it may also make sense to have bootc install generate-iso.

TODO items:

  • Add support for e.g. --copy-network type flows as well as dynamic overlays #22
  • Implement ppc64le and s390x (needs code from both coreos-assembler and coreos-installer)
  • support installing from SELinux-disabled hosts (needs Add support for forcing on selinux labels ostreedev/ostree#2804 )
  • Support overwriting disk we used to boot (systemctl switch-root to container image?)
  • Support basic partition configs (e.g. /var)
  • Related, investigate https://www.freedesktop.org/software/systemd/man/systemd-repart.html
  • Also support running Ignition from the "install boot"; this would make debugging Ignition configs dramatically nicer
  • Ensure we lock devices when partitioning https://systemd.io/BLOCK_DEVICE_LOCKING/
  • Support config files (e.g. distro default filesystem specified in /usr/lib/bootc/install.cfg)
  • Support (or default) to only installing EFI if booted that way, etc.
  • Support systemd-boot
  • Clean up/refactor install code to be more distribution-independent in general
  • Consider merging bootupd in here as e.g. bootc bootloader update or so?
  • Documentation
  • Tests
  • More explicitly test host/target kernel compatibility (e.g. filesystems)

In this case, we shouldn't have anything to do.  This is needed
for `bootc install` which currently sets up these kargs in advance.

mount: /sys/fs/selinux: mount point does not exist.

OK yeah. Let's see if we can support the exciting case of also installing from systems with SELinux disabled...

OK yeah, this path of testing bootc install from the ubuntu system needs ostreedev/ostree#2804

So, going to instead look at doing CI on Fedora for that.

OK, we now have a CI test that proves this works. I think it's about time to get this merged and do further followups (there'll be a lot) as distinct PRs on top of a proven working base. Lifting draft!
