Package: live-helper Version: 1.0~a38-1 When I invoke lh_config with an invalid option, all it says is 'internal error'. Changing line 635 as follows helps: Echo_error "Invalid option $0" Also, it appears the --mirror-bootstrap-security option is no longer valid, which is how I discovered this problem. I'm running sid, up to date as of today, with kernel 2.6.24-1-686 and libc 2.7-8. Thanks! Will
