Subject: [pbs-devel] [RFC v2 pxar 01/36] format/examples: add PXAR_PAYLOAD_REF entry header
Date: Tue, 5 Mar 2024 10:26:28 +0100 [thread overview]
Message-ID: <20240305092703.126906-2-c.ebner@proxmox.com> (raw)
In-Reply-To: <20240305092703.126906-1-c.ebner@proxmox.com>
Introduces a new PXAR_PAYLOAD_REF entry header to mark regular file
payloads which are not encoded within the regular pxar archive stream
but rather redirected to a different output stream.
The corresponding header marks the entry containing all the necessary
data for restoring the actual payload from the dedicated payload stream.
