\fBostree admin unlock\fR [OPTIONS...]
|
|
.SH "DESCRIPTION"
|
|
.PP
|
|
Remove the read\-only bind mount on
|
|
/usr
|
|
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\&.

.SH "OPTIONS"

.PP

\fB\-\-hotfix\fR
|
|
.RS 4
|
|
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
|
|
sshd\&. 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)\&.
