zelta.envzelta.env stores defaults that apply across commands: SSH behavior, logging, snapshot naming, send/receive options, and retention defaults.
Zelta reads user-local configuration under ~/.config/zelta when present; otherwise it uses /usr/local/etc/zelta. You can override locations with ZELTA_ETC, ZELTA_ENV, and ZELTA_CONFIG.
This file uses Bourne shell syntax: KEY=value. For the configuration overview, see Environment & Policy Files. For the option reference, use zelta help options or zelta-options(7).
