I do not alter the root account in any way other that to allow logins
and ssh is configured to only accept passwordless logins for root. 
When I have need to login as root then I run bash from the default
shell and do my work there.

I have dealt with cron by specifying SHELL=/usr/local/bin/bash in
root's crontab.   I am not fond of shell scripts although I have
written many.  Most of what I put into cron jobs are one-liner shell
commands and in my case I have written these for bash.
