fix(glyph): parallelize mcpjungle server registration#343
Merged
Conversation
The mcpjungle-register oneshot service registered 9 servers sequentially, each polling up to 60s for availability. This blocked nixos-rebuild switch for up to 9 minutes in the worst case. Run each registration in a background subshell so all servers are polled concurrently, reducing worst-case wait to 60s. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The mcpjungle-register oneshot service was in multi-user.target, causing nixos-rebuild switch to block until all 9 MCP servers were polled and registered (up to 60s even with parallel registration). Replace the direct wantedBy with a systemd timer that fires 5s after activation. The timer start/restart is instant so activation never blocks. The timer has restartTriggers based on the server config hash, so adding/removing servers re-triggers registration. The service itself has restartIfChanged = false to prevent NixOS from directly restarting (and blocking on) the oneshot during activation. Also parallelizes registrations within the script and removes RemainAfterExit since the timer handles re-triggering. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Type=oneshot causes systemctl start to block until the script completes. Changing to Type=simple makes systemctl start return immediately — the registration script still runs to completion in the background. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
