Sounds good :o)

Wow, sounds great then, I just need to put bags of RAM and tweak
readahead to load what I am interested in.
Only problem is that readahead does not exist in Warty, didn't find it.
However I have Hoary on a another drive, and it appears to have it.
One more reason to switch to Hoary when it's released then...

Thanks for the info...
