* feat: add "--set-version" option This feature will allow to chose a specific cis version to run, like debian 11 or debian 12 * chore: configure current repository as a version And use it as default version. To this end, the scripts in bin/hardening have been made generic by removing the associated recommendation number. Only impact is if you are used to execute scripts directly from bin/hardening. In this case, please use the "bin/hardening.sh" wrapper as intended. I had to rename 2.3.1_disable_nis.sh to uninstall_nis.sh, as it was conflicting with 2.3.1_disable_nis.sh Also, there was a doublon between 1.1.1.8_disable_cramfs.sh and 99.1.1.1_disable_cramfs.sh ; the former was kept * chore: remove CIS recommendation numbers from bin/hardening scripts * fix: some tests are failing find_ungrouped_files.sh and find_unowned_files.sh tests can not be executed multiple times: - test repository is not cleaned - configuration is updated multiple times Those tests are also failing, because: - the sed to change the status in the configuration was also changing the test folder path. - missing /proc in EXCLUDED paths - the EXCLUDED configuration doesn't have the correct format for egrep --------- Co-authored-by: Damien Cavagnini <damien.cavagnini@corp.ovh.com>
