I'm in the process of migrating to key's for authentication on my CentOS boxes. I have it all set up and working, but was a bit taken aback when I noticed service (and other things) didn't work the way I was accustomed to. Even after su'ing to root, still had to call the full path for it to work (which I assume to be expected/normal behavior).

I also assume this is because there are different $PATH's for root (what I was using and am used to) and the newly created, key-using user. Specifically, I noticed the sbin's of the world missing from the user path.

If I were to add those paths (/sbin/,/usr/sbin/,/usr/local/sbin) to a profile.d .sh script for this new key-loving user, would:

1. I be opening up the system in ways I shouldn't be?
2. I be doing something I needn't do save for reasons of laziness?
3. I create other potential problems?

Thanks.
