<title>You can turn off the power anytime you want...</title>
<para>
At the time of this writing, it's common for released versions
of mainstream operating systems (the Playstation OS, Microsoft
Windows, Debian GNU/Linux, and Red Hat Enterprise Linux) to have
non-atomic upgrades; that is, the good ones pop up a screen that
says "Please do not turn off the power". The bad ones don't
even tell you that it's unsafe. The <emphasis>really</emphasis>
bad ones actually mutate your running filesystem without taking
precautions to prevent corrupting running processes.

In contrast, OSTree is designed to implement fully atomic and
safe upgrades; more generally, atomic transitions between lists
of bootable deployments. If the system crashes or you pull the
power, you will have either the old system, or the new one.
