Subject: [pbs-devel] [PATCH proxmox-backup v2] client: mount: flush output before exiting
Date: Fri, 14 Jun 2024 11:39:39 +0200 [thread overview]
Message-ID: <20240614093940.149087-1-g.goller@proxmox.com> (raw)
When using the `proxmox-backup-client mount` command, the parent sometimes
exits before we can print any error message. Most notably this happens
when no PBS_REPOSITORY is passed, as this is the first option checked.
Flush the stdout and stderr so that we can guarantee the output.
