Mladen,

The proc is virtual file system that doesn't take any space on your HD.
The /proc is only mount point for procfs (proc file system).
The /proc/kcore doesn't occupy any space on HD. It is representation of
computer RAM.

What YaST reports is real HD space, and 5GB for SUSE is not that much.
My installation is not very big and it takes 6GB.
You can use command line tools to see what is taking most of the space.
Look in:
#man du
for options for du (disk usage) and see
#df
to see how much space you have on all mounted media.
The df is very fast, but gives only per partition/media usage.
It reports real disk space only.
The du is rather slow if you want details for whole HD, but it reports all
mounted file systems if you don't limit scope using options.

I find usefull
#du -kx --max-depth=1 <here_directory_you_ want_to_check>
For instance:
#du -kx --max-depth=1 /
will list the biggest users of disk space in root directory, skipping
virtual file systems, network mounted disks etc. That will give you real
usage of your hard disk.
