Two webui-data generators wrote to a temp file via bare `cat > "$temp_file"`
then `runFileOp mv` to the final path. The temp file's path sits inside
$containers_dir/libreportal/frontend/data/<x>/generated/ — owned by the
dockerinstall user (the data plane). The generators run as the manager,
who can't open paths under that tree for write, so every WebUI update
hit:
webui_backup_migrate.sh: line 125: …/migrate.json.tmp.<pid>: Permission denied
mv: cannot stat '…/migrate.json.tmp.<pid>': No such file or directory
webui_peers.sh: line 23: …/peers.json.tmp.<pid>: Permission denied
mv: cannot stat '…/peers.json.tmp.<pid>': No such file or directory
Pipe the heredoc through `runFileWrite "$output_file"` instead — same
shape the 5 sibling generators in this dir (backup_app_status,
backup_locations, backup_passwords, backup_snapshots, backup_dashboard)
already use. runFileWrite routes the write via the install user that
owns the data tree, so the file lands on disk in one step (no temp +
mv dance needed). The unused `local temp_file=...` declarations dropped
out cleanly.
The trailing `runFileOp chmod 644 "$output_file"` stays — it's the only
guarantee the WebUI container (which reads these files RO) sees them as
world-readable regardless of dockerinstall's umask.

A peer is a named reference to another LibrePortal instance. Phase 2 only
implements kind=backup-channel (friendly label over a hostname that shows
up in a shared backup repo); direct-ssh-direct and direct-ssh-via-relay
(Connect's blind-relay) are reserved enum values for Phase 3.
DB schema (db_create_tables.sh):
CREATE TABLE peers (
id INTEGER PRIMARY KEY AUTOINCREMENT,
name TEXT UNIQUE NOT NULL,
kind TEXT NOT NULL DEFAULT 'backup-channel',
config_json TEXT NOT NULL DEFAULT '{}',
status TEXT DEFAULT 'unknown',
last_seen TEXT,
created_at TEXT DEFAULT CURRENT_TIMESTAMP
);
+ indexes on name and kind.
config_json is kind-specific so new transports don't need a schema
migration. For backup-channel it carries {"hostname":"","loc_idx":N}.
Bash module (scripts/peer/):
peer_helpers.sh _peerDb, peerSqlEscape, peerValidateName/Kind.
peer_add.sh peerAdd <name> <kind> [k=v ...] → INSERT, refresh
generator. Rejects unimplemented kinds early so users
don't create dead-end peer records.
peer_remove.sh peerRemove <name> → DELETE.
peer_list.sh peerList → JSON array; peerGet, peerNameForHostname
(reverse-lookup for the migrate-tab overlay).
peer_check.sh peerCheckReachable, peerCheckAll. For backup-channel
'reachable' = at least one snapshot from that hostname
visible in (preferred|any enabled) location. Updates
status + last_seen so UI dots render without re-probing.
CLI (scripts/cli/commands/peer/):
libreportal peer list
libreportal peer get <name>
libreportal peer add <name> backup-channel hostname=<host> [loc_idx=<n>]
libreportal peer remove <name>
libreportal peer check [name]
Auto-routed by cli_initialize.sh's category-discovery.
WebUI data generator (scripts/webui/data/generators/peers/webui_peers.sh):
Emits data/peers/generated/peers.json with the peerList output and a
generated_at envelope. Hooked into webuiLibrePortalUpdate alongside the
backup generators.
Frontend:
- New top-level /peers route in spa.js (PeersPage class, peers-content.html).
- 'Peers' nav item in the topbar between Backups and the right-side controls.
- Add-peer modal with friendly-name + kind + hostname + preferred-location
selector (populated from the existing backup-locations data).
- Per-peer card with status dot, last-checked time, Check + Remove buttons.
- Phase 3 kinds appear in the kind dropdown as disabled options so users
can see what's coming.
Source-array wiring:
- generate_arrays.sh auto-created files_peer.sh from the new peer/ dir.
- cli_files.sh + app_files.sh include ${peer_scripts[@]} alphabetically.
- files_webui.sh auto-picked-up the new peers/ generator subfolder.
The migrate-tab friendly-name overlay (use peer names in /backup/migrate
when a peer record exists for a hostname) is intentionally deferred — it's
a 5-line frontend lookup once peers.json is loaded; cleaner to add after
Phase 3 ships its peer-detail view.
