[Buildroot] [PATCH v3 0/7] Container - Guest

[Francois Perrad]

Buildroot supports some OS-level virtualization tools: Docker, LXC, systemd-nspawn.
These tools are built on an host image.

This series introduces a set of defconfig in order to create a guest image.

After some experiments, packages docker & systemd need some tweaks.

v2 -> v3:
  - more examples in readme.txt (including Dockerfile from SkiffOS)
  - select BR2_PACKAGE_CGROUPFS_MOUNT conditional

RFC -> v2:
  - refactor with FOO_LINUX_CONFIG_FIXUPS (new in 2020.05)
  - add option BR2_PACKAGE_SYSTEMD_GUEST

Francois Perrad (7):
  configs/guest_*: some new defconfig
  board/guest: documentation and sample files
  package/docker-engine: needs some kernel options
  package/docker-engine: needs more runtime dependencies
  package/systemd: needs kernel options
  package/systemd: add an option BR2_PACKAGE_SYSTEMD_GUEST
  configs/guest_*: use BR2_PACKAGE_SYSTEMD_GUEST
