Description of problem:
During rescue one must often change CD which is currently not possible. Doing
a "umount /mnt/source" or simliar gets "Device or resource busy" and prevents
you from using a different CD.
Different CDs are important if you want to install/repair a rpm found on the
second rhat disk or if using a "private" cd containing dumps/tars to restore.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot rescue
2. Try to unmount cdrom
Actual Results: Device or resource busy
Expected Results: unmounting
Not possible. The rescue image you are working off of is on the mounted CD. If
you want to use the CD during rescue mode for other things, you need to use a
network method such as FTP, HTTP, or NFS for rescue mode.
Think about copying the files into a ram disk. Would be easy and of great helf.
