|
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).
