(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
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!
