Re: [uml-user] hang after Starting crond: [ OK ]
Thank you very much for your patient and nice advice. I follow your advice: I have updated the images on the website. To update an existing one (Fedora 13 or 14), loop mount it then chroot and run: mknod /dev/tty0 c 4 0 echo tty0 /etc/securetty sed -i -e 's/1-6/0-6/g' /etc/sysconfig/init sed -i -e 's/1-6/0-6/g' /etc/init/start-ttys.conf * and it really work! Many thanks!
