post-unlock — Notification of a successful path unlock.
The post-unlock
hook
runs after one or more paths have been unlocked. It is typically used
to send email notification of the unlock event.
If the post-unlock
hook
returns a nonzero exit status, the unlock will
not be aborted, since it has already completed. However,
anything that the hook printed to stderr will be marshaled back to the
client, making it easier to diagnose hook failures.
