.SH "NAME"
ostree-admin-unlock \- Prepare the current deployment for hotfix or development
.SH "SYNOPSIS"
.HP \w'\fBostree\ admin\ unlock\fR\ 'u
\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)\&.
