Thanks! Both the man page, and the info pages for tar are incredibly hard to decipher. I did like you told me and now have /usr resting comfortably on sdc1. I found another gig or so of out-of-date updates and got rid of them too, so for now i just renamed the old /usr to (can you guess? that's right!) /old.usr
Afetr I'm happy that everything transferred correctly I can rm -rf old.usr and free up another 4.4G. (Half my hard drive is in /usr! Ack!) Thanks again!
