Link sub-folder to seperate partition

[Paul Trevethan]

I hope I can explain what I want to achieve here without sounding
utterly stupid?

I have a large hd on my desktop system. I run Ubuntu 6.06 as my primary
os under ext3 filesystem. I have an 80Gb partition that I currently use
for loading other os's; for experimenting and learning, etc, etc -
currently has latest Mepis on it. Everything important is backed up
regularly to external usb drives on a Linksys NSLU2 using 'Simple
Backup'.

I have settled on Ubuntu as my os going forward, so the extra stuff is
used less and less and I am thinking of dropping the partition size to
say 20Gb for os stuff and use the balance as my multimedia (particularly
movie) storage area.

I have been trying to learn how to make movies (dvd) from masses of
family photos and from tv shows recorded on my set-top box. These need
to be demuxed, re-created as mpg's and burned to dvd. These files can be
quite large and so I thought I would seperate them out from the
normal /home stuff. At the same time I thought I might have a look at
JFS as a filesystem.

The partitioning & formatting is ok; I know what to do there with
QTparted. However, I would like the new partition to still look like it
is part of my /home tree structure. So, if I cd to /home/paul/movies
(say) it goes and looks at the other partition but still appears in
nautilus under /home/paul.

My question is: is this possible?

I would think I would have to adjust my mount parameters in fstab; but
can I give the new partition a mount point inside /home? Perhaps mount
it quite seperately and create a link of some sort
from /home/paul/movies to the new partition?

Any guidance appreciated.

Also, any experience on whether JFS is a good choice for fs when files
will tend to be large and may be lots of deleting going on (as I learn
software)?

Thanks,
Paul.
