I was mistaken about what we were talking about. Let me see if I have it right now:

An alias would let me make whatever command I want equivalent to bitcoind -datadir=/mnt/storageraid/.bitcoin/ getinfo

What I thought you were talking about, and what I meant in my last post is a link, not an alias.

I am hoping to run bitcoind in the home directory (the default), and replace block data like blk00001.dat with a link to /mnt/storageraid/.bitcoinstuff/blk00001.dat

I am not sure if this will work as I am expecting, and I also do not know what all files I would need to relocate and link to achieve this.

Thanks again, and sorry about the confusion
