Another thing you might consider;

You have /usr sized at 13.5G - which allows plenty of room on /usr.
Then you mount hdc3 at /usr/local which effectively limits /usr/local to
2.4G, you would have a lot more room on /usr/local if you didn't make
this a different file system.  You do the same thing with /usr/src.

I would make /usr/local and /usr/src just subdirectories which would
free up the hdc3 and hdc5 partitions (maybe make one of these the /opt
file system.)

/usr/local is the normal location to install tarballs so it has a
tendency to fill up pretty quickly if you install a lot of them. I
have about 8G installed on /usr/local.  

On Mandrake /usr/local also contains an auxillary heirachy  -
/usr/local/etc, /usr/local/bin, /usr/local/lib /usr/local/man,
/usr/local/src, /usr/local/sbin, and /usr/local/doc directories, which
can fill a drive pretty quickly.

Anyway, it's just something to consider.  By the way where is hdb ?
