## Further reading
I've been pointed to
[this StackExchange answer](http://unix.stackexchange.com/questions/226872/how-to-shrink-root-filesystem-without-booting-a-livecd/227318#227318)
which details how to manually perform a similar process, but using a subset of
the existing root filesystem instead of a rescue filesystem. This allows you
to keep (a new copy of) the existing init system running, as well as essential
daemons, and then go back to the original root filesystem once you're done. This
is a more useful version if, for example, you want to resize the original root
filesystem or re-configure disk partitions, but not actually install a different
distro, and you want to avoid rebooting at all.
`takeover.sh` could be extended to support re-execing a new init once you're
done. This could be used to switch to a *new* distro entirely without
rebooting, as long as you're happy using the old kernel. If you're interested,
pull requests welcome :-).
