Re-read partition table without reboot?

[Realos <realos@loftmail.com>]

In order to solve the problem of tiny free space on my hard drive, I was
thinking about adding a new partition on the directory tree.
Original post about disk space problem ---> http://lists.debian.org/debian-user/2005/11/msg01982.html

I have found some free space on my hard drive that I would like to
partition and mount to /var. But AFAIK partition re-read only occurs after
reboot. I do not like to reboot if possible.

Is there a way out??

cheers,
