There's more than just separate file systems to consider. Every file that *has* to exist before you can get to a root file is one more file that can force you to more extreme measures if it gets corrupted. Since you shouldn't be doing a lot as root, there's not much point in adding that risk if you don't have to. > > Edit /etc/passwd and change the /bin/sh or /bin/csh or what-have-you to > > whatever you want your shell to be. > /etc/passwd is generated from /etc/master.passwd.

You might note that the actual sequence for many things is VISUAL (if set), the EDITOR. This is true for vipw, even though the man page doesn't mention it. The idea was that you would get VISUAL if your termain could support a visual editor, otherwise EDITOR. For bash, you can add that .profile, and other things will inherit it. <mike To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
