/tmp is a RAM-backed tmpfs on Ubuntu (50% of RAM). Agent runs fill it: half the RAM goes, then every temp-file creation fails with ENOSPC and shells break. Swap does not lift the cap, so the fix is /tmp on disk. End-of-install offers (Linux, [y/N], skipped without a terminal, idempotent): - offer_tmp_on_disk: mask tmp.mount + etc/tmpfiles.d/tmp.conf (wipe at boot, 10-day purge, /var/tmp rule kept). Effective at next reboot. - offer_ssh_memory_guard: the previous server's rules. ssh.service drop-in (OOMScoreAdjust=-1000, MemoryMin=256M) + earlyoom with --avoid sshd and --prefer node/java. MemoryMin covers sshd only; earlyoom is the real guard. install_cloudpex deploys the NAS mount helper in the Linux block. Docs: README steps 12-14 + table, CLAUDE.md layout + lint command.

# CLAUDE.md — config (personal dotfiles)
|
|
|
|
Project context for Claude. Global preferences in `~/.claude/CLAUDE.md` apply on top.
|
|
|
|
## What this is
|
|
|
|
Personal dotfiles repo. **Archetype: dotfiles-meta** (meta/config, not an application).
|
|
Produces vim + bash configuration deployed by `install.sh`. Private/personal audience.
|
|
|
|
- Public: no
|
|
- Database: none
|
|
- Stack: POSIX/bash shell scripts + vimscript
|
|
- Distribution: `git clone` + `./install.sh` (OS auto-detected)
|
|
|
|
## Layout
|
|
|
|
```
|
|
remote-install.sh curl|bash bootstrap: ensure git, clone/pull, run install.sh
|
|
install.sh one-shot installer (OS auto-detected)
|
|
vim/vimrc vim config (pathogen, molokai, syntastic, NERDTree)
|
|
vim/autoload/ pathogen loader (committed)
|
|
vim/colors/ molokai colorscheme (committed)
|
|
bash/bashrc-{linux,osx} OS-detected bashrc
|
|
bin/{dt,dtach-router,claude-provider} CLI scripts deployed to ~/.local/bin
|
|
etc/profile.d/disk-usage-warning.sh login-time low-disk warning → /etc/profile.d (Linux only)
|
|
etc/tmpfiles.d/tmp.conf disk-backed /tmp cleanup rules (offer: /tmp on disk)
|
|
etc/systemd/ssh.service.d/override.conf sshd OOM-exempt drop-in (offer: SSH memory guard)
|
|
etc/default/earlyoom earlyoom args, spare sshd / kill node first (same offer)
|
|
cloudpex/{cloudpex,install.sh,README.md} on-demand CloudPex SMB mount helper → /usr/local/bin (FR docs)
|
|
.claude/{tasks,memory,audits}/ Claude working state
|
|
```
|
|
|
|
`/tmp` is a RAM-backed tmpfs on Ubuntu (50% of RAM): agent runs fill it, which is why
|
|
install.sh offers to mask `tmp.mount`. Swap is not the fix (the cap and ENOSPC stay).
|
|
|
|
`pymupdf`/`markdown_py` are NOT tracked — they are pipx entry-point shims,
|
|
recreated by `pipx install PyMuPDF Markdown` in install.sh.
|
|
`claude-provider` reads `$OPENROUTER_API_KEY` from the env — never hardcode it (the
|
|
original had a live key; it was scrubbed — see decisions/blockers).
|
|
|
|
## Commands
|
|
|
|
| Task | Command |
|
|
| ----- | ---------------------------------------- |
|
|
| Lint | `shellcheck *.sh cloudpex/install.sh cloudpex/cloudpex bash/bashrc-*` |
|
|
| Syntax check | `bash -n install.sh remote-install.sh cloudpex/install.sh` |
|
|
| Install | `./install.sh` (OS auto-detected) |
|
|
| Remote install | `curl -fsSL <raw>/remote-install.sh \| bash` |
|
|
|
|
No build, no test suite. Lint = shellcheck.
|
|
|
|
## Conventions
|
|
|
|
- Shell scripts: `#!/usr/bin/env bash`, `set -euo pipefail`, quote all expansions, keep shellcheck clean.
|
|
- Installer must stay **idempotent** (re-runnable without breaking state) and use `$SCRIPT_DIR`-relative paths.
|
|
- bashrc files: tabs for indentation (existing style). Style nits (legacy backticks) tolerated — don't churn.
|
|
- No secrets in any tracked file. Use placeholders if config ever needs tokens.
|
|
|
|
## Known issues (see .claude/audits/ONBOARD_REPORT.md)
|
|
|
|
- `vim/vimrc` `GenerateClassC` uses bare `name` instead of `a:name` → `:ClassC` errors (E121). Vim domain, not yet fixed.
|
|
- bashrc files use legacy backticks (`SC2006`) — cosmetic.
