The only concern with doing so is that doing so causes the (larger!) bash-static kernel to be used everywhere. If you have lots of regular users with console prompts, this could be painful. I haven't done this, but it should be possible to instal l both bash-static and bash. One would have to rename the first (bash-static) to something other than 'bash' and add that to the /etc/shells file, but after doing so also install the bash package with the non-monolithic binary 'bash' and use that as the shell for regular users. Have I forgotten any concerns or steps in doing so? It seems to me that the benefits of having full bash capability available for the toor user, and having regular bash available (as opposed to sh or tcsh) for regular users has marked advantages for users (such as myself!) who are not csh adepts. Brandon, this is getting esoteric.

I use bash for my user and root shell. To deal with mishaps I set my she= ll in passwd to sh and create a small .profile which mainly just has this li= ne: bash && exit 0 That way if bash is fine I run it and immediately exit when it does. If bash is missing or can't run then the exit is skipped and I am in sh so t= hat I can fix things. --=20 D'Arcy J.M.
