That looks good. But I still wish you had done what I asked and provided

I am still puzzled as to why this fix solves the library problem. I wish
you had answered my earlier question about where the ncurses5 library is
kept on your system.

The commands you transcribed below are incomplete and should not work. Not
any of them. I asked you to provide the output of "ls -l /" this time
around, and you did not. Please do so, along with a correct transcription
of the commands you are using to create the symlinks.

What does "ff" mean? You use it several times.

As I wrote above, these are incomplete. They should be of the form
ln -s /mnt/hda6/usr /usr
It is possible that your current problem arises from nothing more than your
entering 3 of the commands correctly and the fourth (the one for /var)
incorrectly.
Or you may have entered them too late ... after syslogd has started.
Or you may have removed the actual /usr, /tmp, and /home directories,
allowing ln -s to recreate them as symlinks ... but forgotten to remove
/var (this *might* be what you mean by "has been created auto" below),
which would cause even a correct symlink command to fail.
Or some other init script may be doing something (for example, noticing
that /var is absent and creating it) that interferes with your symlink
approach.
Or maybe something else. It's hard to say without more detail.
Please, next time, provide the diagnostics I ask for, instead of (or in
addition to) the ones you think are interesting.

I don't know what this sentence means, specifically the phrase "running
file command on the links :-".

I assume we are talking about a normal multi-user boot/init here (another
thing you may recall my asking you to be specific about in my prior
response). In any case, it is impossible to interpret these messages when
you tell us neither what they say or when in the boot/init process they
appear. For example, are the messages really about /var, or might they be
about /var/log ?

mount -o remount,ro /dev/whateveritis /usr
is one way. Read the man page for mount for the details.
But remember that in your setup, your /usr directory is *not* its own
partition (which is why I used the "somethingorother" above, lacking a real
example from your system).

OK. As I aked before, I want to see the output of ...
ls -l /
df
find / -name libncurses* (I didn't give the actual
command before; I
just asked where libncurses5 was
located)
... and all actual error messages (not summaries or paraphrases) that you
see.
Also, please provide the output of
ls -l /mnt/hda5
ls -l /mnt/hda6

Hi !
Thank you all for the help .
I again tried by removing the old links & recreating them in single user
mode .
cd /
ln -s /mnt/hda5/var
ln -s /mnt/hda5/tmp
ln -s /mnt/hda6/usr
ln -s /mnt/hda6/home
This time everything worked fine & my sytem is up & running.
