<pre>
A PersistentDirectory backed by a Compute Engine regional persistent
disk. The
[persistent_directories][google.cloud.workstations.v1beta.WorkstationConfig.persistent_directories]
field is repeated, but it may contain only one entry. It creates a
[persistent
disk](https://cloud.google.com/compute/docs/disks/persistent-disks) that
mounts to the workstation VM at `/home` when the session starts and
detaches when the session ends. If this field is empty, workstations
created with this configuration do not have a persistent home
directory.
