**new** utils/lib_install.sh:
Used to initialize installation procedures
- Modified source_dot_config function that
- loads .config.sh from an existing installation (at SEARX_SRC).
- initialize **SEARX_SRC_INIT_FILES**
- functions like:
- install_log_searx_instance()
- install_searx_get_state()
**modified** utils/searx.sh
- obsolete environment SEARX_INSTANCE_NAME has been replaced
by string 'SearXNG'.
**modified** utils/filtron.sh, utils/morty.sh, utils/searx.sh
- source utils/lib_install.sh
- normalize logging of environment variables using new function
install_log_searx_instance()
**modified** utils/lib.sh
- fix marginal typos
**Installation scripts**
The utils/lib_install.sh is sourced by the installations scripts:
- utils/searx.sh
- utils/morty.sh
- utils/filtron.sh
If '${SEARX_SRC}/.config.sh' exists, the modified source_dot_config() function
loads this configuration (instead of './.config.sh').
**SEARX_SRC_INIT_FILES**
Array of file names to sync into a installation at $SEARX_SRC. The file names
are relative to the $REPO_ROOT. Set by function init_SEARX_SRC_INIT_FILES().
Most often theses are files like:
- .config.sh
- searx/settings.yml
- utils/brand.env
- ...
