[ale] need help to correct duplicate mount entries?

[Sean Johnson]

Hi, i need help understanding why i have multiple mount entries on
/etc? I recently created a separate partition for /etc because i
thought i could share it between Ubuntu (my main system) and Kubuntu
(didn't work as planned). I copied the /etc from my original Ubuntu
partition into the new /dev/hda7 and then changed fstab to mount /etc
on that device. I appear to have missed something basic? I found this
article:

http://linuxgazette.net/issue64/tag/12.html

which suggests i may have copied the /proc file system multiple times
by accident.

Partitions:
hda1 -- old Libranet
hda2 -- currently used Ubuntu
hda6 -- Kubuntu
hda7 -- supposed to be shared /etc partition

(parted) print

Questions:

1. how can i correct this error i have apparently made? 
2. Is it possible or practical to share /etc between these 2 distros?
3. Is ext2 the best file system (smaller) or reiserfs (bigger) for
/etc partition?
