No Ed,
I tried sudo first then swithed to root on Knoppix. In fc5 I logged in as
root. Still read only file systems

Knoppix mounts file systems read only for your protection. You must
specifically right-click and make each file system read/write when
using the Knoppix boot CD. The right-click menu has changed so you may
need to look carefully at all of the options.

The following note, borrowed from here should help you out:

Rescuing a non-booting Linux system

This is the most common scenario. Something goes haywire, and boom, no
boot. No problem: boot up Knoppix and find all your local partitions
nicely iconicized on the KDE desktop. (Or cruise the file tree to
/mnt.) Click on the correct icon, and there are all your files. But
they are wisely mounted read-only. Again, no problem: right-click the
desktop icon to bring up a nice menu with a "Change read/write mode"
option. This mounts the filesystem on the partition as read/write. Now
you can edit any file.

The default user is knoppix. For operations that require root
privileges, you need to su to root and assign a root password:

 [email protected][knoppix]# su
 [email protected][knoppix]# passwd

To mount a filesystem read/write from the command line:

 [email protected][knoppix]# mount -t reiserfs -o rw  /dev/hda5  /mnt/hda5

To unmount:

 [email protected][knoppix]# umount /mnt/hda5

If you get an error message "Could not unmount device, device is
busy," something is reading the filesystem. Close files and cd out of
the filesystem.

How do you know what mountpoint and filesystem to specify? Just read

 [email protected][knoppix]# cat /etc/fstab
 # Added by Knoppix
 /dev/hda5 /mnt/hda5 reiserfs noauto,users,exec 0 0
