I don't think you can do it on a live system, so you migh need to do it from a rescue session (linux rescue from the CD1) but ymmv. good luck Tru -- Tru Huynh (CentOS-3 i386/x86_64 Package Maintenance) http://pgp.mit.edu:11371/pks/lookup?op=get&search=0xBEFA581B -------------- next part -------------- A non-text attachment was scrubbed...
