Distros reserve /opt for different things (some package managers own it
outright), and a DECNET install that wants to live at /srv/decnet or
/usr/local/decnet had to hand-edit 13 service files post-install.
Converts every deploy/decnet-*.service to a .j2 template keyed on
{{ install_dir }}, rendered by `decnet init` at install time. All other
paths (log_dir, state_dir, runtime_dir, user, group) stay standard —
only install_dir varies.
Changes:
- deploy/decnet-*.service → deploy/decnet-*.service.j2 (13 files).
- decnet init gains --install-dir (default /opt/decnet, preserves
existing behaviour byte-for-byte). Validates absolute-path at the
CLI boundary. Threads through useradd --home-dir and the dir-creation
list so the filesystem layout matches the rendered templates.
- _install_units renders via Jinja2 with StrictUndefined (typo → loud
error, not a silent broken unit). SHA over rendered output so
operators with a custom install_dir get idempotent re-runs.
- decnet.target, tmpfiles.d, polkit rule stay static — they don't
reference install paths.
- 4 new tests: custom install_dir renders into units, default remains
/opt/decnet, relative paths rejected, second run with same custom
dir is idempotent.
