Re: [gentoo-user] No working burning cdrom
It works again! Question is why emerge/k3b installed/changed permission with suid bit. It is a bug? AFAIK, K3b by default gives the suid bit to growisofs and other cd recording programs. It complains if it finds these programs without the suid bit and asks you to set it for you, however, so you should have seen it (It needs your root password to do it, so it's interactive :) ) m. -- gentoo-user@gentoo.org mailing list
