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.
