# Manual System Overrides

This document tracks all persistent system changes implemented manually that are not (yet) managed via Ansible roles.

## Principles
1. **Ansible First**: Always prefer automation over manual overrides.
2. **Document Everything**: Any manual change MUST be recorded here with rationale.
3. **Migrate to Code**: Periodically review this list to identify candidates for Ansible migration.

## Active Overrides

| Date | Change | Rationale | Ansible Status |
|------|--------|-----------|----------------|
| 2026-07-03 | Patched `remmina-plugin-rdp.so` in `~/.config/remmina/plugins/` | Remmina 1.4.43 crashes (SIGSEGV) on Wayland when `keymap` is set in a profile. Built from `~/external/remmina/` fork with NULL check fix. Alt plugin dir loads before system plugin. MR !2757 submitted upstream. See `docs/learnings/2026-07-03-remmina-wayland-crash-fix.md`. | Remove when upstream fix is released and packaged |
| 2026-06-17 | Discovered and deleted `br_vm_internal` bridge (10.10.2.0/24) | Externally-created bridge, no NM config file, no VMs attached. Origin unknown — likely ad-hoc `nmcli con add` or manual `brctl` session (Jun 10). Traffic-shaping qdisc (`htb`) suggests prior VM network isolation attempt. Deleted via `nmcli con delete` + `ip link delete`. | N/A (removed) |
| 2026-04-02 | Moved LLM models to `/home/mw/models/` (SATA SSD) with symlinks | Free root NVMe space (93%→87%, +25G freed) | Not yet |
