+You can overwrite defaults:

On GNU/Linux, the default is to boot directly to the kernel; this has
the advantage of requiring only a very tiny root disk image since the
store of the host can then be mounted.

The manual already states (info "(guix) Invoking guix system"):
--8<---------------cut here---------------start------------->8---
‘vm’
Build a virtual machine that contains the operating system declared
in FILE, and return a script to run that virtual machine (VM).
Arguments given to the script are passed to QEMU.
--8<---------------cut here---------------end--------------->8---
Perhaps we should add the example to illustrate this last sentence?

Yea, it will be great, because it's not obvious for me and maybe
somebody else. Is current example OK?
