Rescue DVD chroot used to run service* commands up to F14 iirc.
Trying to rescue a couple of Rawhide KVM Guests
Booting the guests from F17-DVD (i386\x86_64 as case may be) > troubleshoot > rescue installed system
chroot --userspec=root:root /mnt/sysimage
Simple things as "service autofs\netfs\gpm start" cannot be done: "Running in chroot, ignoring request"
Cannot be booted normally due to recent cryptsetup upgrade. No "single\rd.debug" doesn't get that far. So it has to be the DVD.
