Vivien Didelot 67763ccd1c systemd-container: recommend tar
If systemd is configured with importd, "machinectl import-*" can be
used to add container trees under /var/lib/machines.

But "machinectl import-tar" makes use of "tar --numeric-owner" which
is not supported by the busybox binary, as shown below:

    # machinectl import-tar /tmp/container.tar.xz
    Enqueued transfer job 1. Press C-c to continue download in background.
    Importing '/tmp/container.tar.xz', saving as 'container'.
    Imported 0%.
    tar: unrecognized option '--numeric-owner'
    BusyBox v1.31.1 () multi-call binary.
    Usage: tar c|x|t [-ZzJjahmvokO] [-f TARFILE] [-C DIR] [-T FILE] [-X FILE] [FILE]...
    Failed to decode and write: Broken pipe
    Exiting.

To fix this, recommend the standard tar package.

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
