Pacstall tried to BUILD neovim from source (downloaded the v0.12.2
tarball and ran the build chain). On a Pi this is 5+ minutes plus
fragile — pacstall's connection broke during download.
Switch to direct binary tarball install:
1. Pinned to NVIM_TARGET_VERSION='v0.11.4' in two places:
- run_once_20-install-user-packages.sh.tmpl (initial install)
- dot_local/bin/update-neovim.sh (topgrade-time updates)
2. Both use the same install logic: detect arch via uname -m, download
the right tarball (nvim-linux-arm64.tar.gz for aarch64), extract
to /opt, symlink /usr/local/bin/nvim. Idempotent — if installed
version == target, no-op.
3. Topgrade config has a [commands] entry that runs the update script
after system updates. To upgrade neovim across all boxes: edit
NVIM_TARGET_VERSION in dot_local/bin/update-neovim.sh, commit,
push, run topgrade.
4. Removed run_once_05-install-pacstall.sh.tmpl entirely — pacstall
isn't worth the install footprint for one package.
Three changes:
1. NEW run_once_05-install-pacstall.sh.tmpl (debian-only)
Installs pacstall via its official installer. Pacstall is an
AUR-like package manager for debian/ubuntu, with neovim at
0.12.2-1 (current as of bootstrap). The installer requires
root and prompts for 'install axel?', so we run it under
sudo with NON_INTERACTIVE=true and stdin redirected from /dev/null.
2. UPDATE run_once_20-install-user-packages.sh.tmpl
On debian, prefer pacstall over the GitHub tarball when
pacstall is available. The tarball fallback remains for the
case where pacstall install failed or isn't wanted.
3. NEW dot_config/topgrade/topgrade.toml
Topgrade's built-in pacstall step auto-detects pacstall and
runs 'pacstall -U -Up' (update repo + upgrade packages).
Built-in chezmoi step also auto-detects chezmoi. So our
topgrade config just sets pre_sudo=true for password caching
and ignore_failures for node.
