(there wasn't a ref-guide component in Bugzilla - sorry) The Reference Guide errata explains the new rescue procedure, but shows the incorrect command to mount your root filesystem: mount -t ext2 /dev/hda5 /mnt This is incorrect. The root filesystem should be mounted on /mnt/sysimage since the rescue mode sets paths using /mnt/sysimage. Mounting on /mnt renders the rescue mode unusable since there are directories under /mnt that are needed. The /mnt/sysimage directory does *not* exist either; it must be created by the user.
on the online 6.2 GSG manual, this mount command example is changed: "However, if your root filesystem is undamaged, you can mount it and then run any standard Linux utility. For example, suppose your root filesystem is in /dev/hda5. Here's how to mount this partition: mount -t ext2 /dev/hda5 /foo Where /foo is a directory that you have created. Now you can run chroot, fsck, man, and other utilities. At this point, you are running Linux in single-user mode."
thanks for your report!
