Unfortunately not.
What you've got is:
/home mountpoint using partition X
/var mountpoint using partition Y
Now, in partition X, you'll have directories like "dazza", "www",
"fred", etc -- that is, every single file and directory in /home is in
that partition. The partition has no inherent knowledge of the fact it
is being used as a /home.
And over in partition Y, you'll have directories like "log", "run",
"spool", and so on -- all the stuff you see under your /var directory.
If you change the /home mountpoint to use partition Y (e.g. by editing
/etc/fstab), what you'll now see if you look in /home will be:
/home/log, /home/run, /home/spool... which is not what you want, of
course.
I think you'll need to do some shuffling with a temporary partition of
some sort, but I'm not really sure of the best way to do that --
hopefully someone else can offer some good suggestions on how to do
that. Basically, you need to copy everything from the small partition
to the big one, and vice versa.
I hope I've made it clear how it works. Feel free to post again if I've
confused you.
