These changes allow for a local rules file that will be preserved across
upgrades and allows the main rules file to be overwritten across upgrades.
- Move all config/rules files below /etc/falco/
- Add a "local rules" file /etc/falco/falco_rules.local.yaml. The intent
is that it contains modifications/deltas to the main rules file
/etc/falco/falco_rules.yaml. The main falco_rules.yaml should be
treated as immutable.
- All config files are flagged so they are not overwritten on upgrade.
- Change the handling of the config item "rules_file" in falco.yaml to
allow a list of files. By default, this list contains:
[/etc/falco/falco_rules.yaml, /etc/falco/falco_rules.local.yaml].
Also change rpm/debian packaging to ensure that the above files are
preserved across upgrades:
- Use relative paths for share/bin dirs. This ensures that when packaged
as rpms they won't be flagged as config files.
- Add CMAKE_INSTALL_PREFIX to FALCO_ENGINE_LUA_DIR now that it's relative.
- In debian packaging, flag
/etc/falco/{falco.yaml,falco_rules.yaml,falco_rules.local.yaml} as
conffiles. That way they are preserved across upgrades if modified.
- In rpm packaging when using cmake, any files installed with an
absolute path are automatically flagged as %config. The only files
directly installed are now the config files, so that addresses the problem.
Add CMAKE_INSTALL_PREFIX to lua dir.
