Nicolas Massé	023618bf62	Let zfs-autobackup decide which domains are configured Before handing a domain over, snapshot-libvirt-domains guarded it behind 'zfs get -s local autobackup:libvirt-<domain>' and tested the result for non-emptiness. That answers neither of the questions that matter. -s local drops exactly the inherited lines, while zfs-autobackup looks the property up without -s and resolves inheritance (ZfsNode.selected_datasets rewrites "inherited from <parent>" to the parent's source, ZfsDataset.is_selected takes an inherited flag). Configuring the fleet once on the parent dataset - the normal way to drive zfs-autobackup, and the only way to cover datasets that already exist without walking them one by one - therefore made zvirt skip every domain, while the very same backup names handed to zfs-autobackup by hand snapshotted all of them. The guard also had no dataset operand, so it asked "does any dataset in the pools carry this property locally?"; and it tested presence where zfs-autobackup tests value, so a local =false passed it, and child/parent were misjudged in both directions. Drop the guard and let zfs-autobackup answer, since it is the one selecting. It reports "nothing selected" as exit 255 with a distinctive message, so keep its stderr aside for the length of one domain, long enough to tell that case (skip the domain, carry on with the fleet, exit 0) from a genuine failure (replay the stderr, abort with its exit code). Its own wording is swallowed in the skip case: it is printed as an error while nothing failed. Document the selection in the README - the four property values, the fact that inheritance counts, and the two properties involved (autobackup:libvirt-<domain> to snapshot, autobackup:libvirt to prune). This does not cover the case of a domain whose selection misses part of its storage: the property selects datasets, not domains, and only zvirt knows what a domain is made of. Tracked in #3.

Nicolas Massé	c4a1d54d86	Make the snapshot name format queryable The snapshot format was hardcoded in snapshot-libvirt-domains, so any tool pruning zvirt's snapshots had to copy the same literal. On a mismatch, zfs-autobackup selects the right datasets, matches none of their snapshots, destroys nothing and still exits 0 - snapshots then accumulate forever while the retention job reports success. Move the format to a sourceable file, /usr/share/zvirt/snapshot-format, that snapshot-libvirt-domains sources instead of hardcoding, so producer and consumer cannot drift. Also expose it as --print-snapshot-format for consumers that would rather not source a file. Document the retention run, the deliberate absence of a {} placeholder (it is what allows a single prune run to cover every domain), and the systemd specifier escaping trap. While here, fix the lint target: bin/*.sh matched no file, since neither script carries a .sh extension.
