<title>Description</title>
<para>
Remove the read-only bind mount on <literal>/usr</literal>
and replace it with a writable overlay filesystem. This
default invocation of "unlock" is intended for
development/testing purposes. All changes in the overlay
are lost on reboot. However, this command also supports
"hotfixes", see below.

<listitem><para>If this option is provided, the
current deployment will be cloned as a rollback
target. This option is intended for things like
emergency security updates to userspace components
such as <literal>sshd</literal>. The semantics here
differ from the default "development" unlock mode
in that reboots will retain any changes (which is what
you likely want for security hotfixes).
