Re: missing space on HDD

Thanks muchly for this, man tunefs wasn't there, but a quick look around found 
man tune2fs, which worked a charm, I now have the count I was expecting.
however, when working on the system, I am logged in as root (and no-one else 
uses this computer while it's running linux), so reserved space isn't really 
as useful on this box.
with it now set to 0% on both ext3 partitions, I'll be able to use that left 
over space 8^)
however, apart from the kernel and a half dozen apps, all the software I have 
for linux is what came in the slack packages, so I could only clean up by 
removing them, or carefully pruning from stuff I installed, eg some of the 
docs that aren't appropriate to me, or storing source away. 

cheers,
Adam

Life would be so much simpler if we could get a hold of the source code
