Oversized auxiliary file systems in Dapper; why?

	Hello everybody,

	When I want to check the available space on my hard disk, I get the 

urtzi at escher:~$ df -h
Filesystem            Size Used Avail Use% Mounted on
/dev/hda1             5.0G  3.5G  1.3G  74% /
varrun                248M   88K  248M   1% /var/run
varlock               248M  4.0K  248M   1% /var/lock
udev                  248M  140K  248M   1% /dev
devshm                248M     0  248M   0% /dev/shm
/dev/hda3              64G   43G   18G  71% /home

	I am quite surprised by the four 248-MB filesystems. I have checked quite 
often, and these filsystems are never more than 1% full.

 	How can I tweak the system to remove or make them smaller (I mean, does udev 
need 250 MB to work at all?)? Do I actually need all of them?

	If it has to be like that, I'd like to know how do I get in exchange for 
losing a whole GB of disk space! ;-)

	It just occurred to me: maybe these four systems are another way to display 
the swap partition? I have a 1 GB swap at /dev/hda2, but I can't see it here.

	Thanks in advance,

	- Urtzi -
