docs(setup): use ~/.bashrc hand-off instead of chsh for zsh switch (#221)
## Summary Follow-up fix on [#220](#220). The corp infra locks the default shell at user-provisioning time on the dev VM (`10.100.201.21`) — `chsh` is denied at the PAM level, so the `sudo chsh -s` block in [`20-zsh.sh`](docs/setup/scripts/20-zsh.sh) fails on every fresh VM. Switch to the `~/.bashrc` exec-zsh hand-off — the same proven pattern used in the legacy [`02-wsl-terminal-setup.md`](docs/setup/02-wsl-terminal-setup.md). UX-identical for the dev, zero infra escalation required. ## What lands | File | Change | | --- | --- | | `docs/setup/scripts/20-zsh.sh` | Drop the `sudo chsh -s` block. Append a guarded `exec zsh -l` block to `~/.bashrc` instead, marked with a managed-by comment for idempotency on re-runs. | | `docs/setup/01-dev-debian-vm-setup.md` | Table row for `20-zsh.sh` updated — "set as default shell" → "`~/.bashrc` (exec zsh on interactive shells — `chsh` is blocked on the corp VM)". | | `docs/setup/README.md` | Same descriptor adjustment. | ## The hand-off block ```bash # Managed by docs/setup/scripts/20-zsh.sh — apf-portal zsh hand-off. # Hand off to zsh on interactive shells. The `case $-` guard avoids # breaking non-interactive bash (scp, rsync, cron, …), and the # ZSH_VERSION check prevents an infinite re-exec loop. case $- in *i*) if command -v zsh >/dev/null 2>&1 && [ -z "${ZSH_VERSION-}" ]; then exec zsh -l fi ;; esac ``` Two safety nets in the block: - **`case $- in *i*)`** — only runs the hand-off when the shell flag set contains `i` (interactive). `scp` / `rsync` / non-interactive ssh executions go through bash and are not hijacked. - **`[ -z "${ZSH_VERSION-}" ]`** — `ZSH_VERSION` is set by zsh itself; if it's already set we're already in zsh and a re-exec would loop. ## Test plan - [ ] On the dev VM, run `20-zsh.sh` on a fresh state: bash, no existing `~/.bashrc` zsh hand-off → script exits without `chsh` error, `~/.bashrc` gets the block appended, `exit` + reconnect lands in zsh. - [ ] Re-run `20-zsh.sh` → reports `↪ skip zsh hand-off already in ~/.bashrc` (idempotency). - [ ] `scp some-file vm-dev:/tmp/` from the workstation still works (non-interactive bash not hijacked). - [x] `pnpm exec prettier --check` clean on the touched markdown files. - [x] `bash -n docs/setup/scripts/20-zsh.sh` (syntax check) clean. ## Why not amend #220 #220 has already merged. Squash-merge collapsed it to `8a04540` on main; a force-push to amend would rewrite that commit and break anyone who's pulled it. The fix lands as a separate commit on the same setup-doc family. --------- Co-authored-by: Julien Gautier <julien.gautier@apf.asso.fr> Reviewed-on: #221
