As I know, root
's default shell is configured csh
and normal user's default shell is sh
in FreeBSD. And in Ubuntu, root
is dash
, normal user is bash
. (refer: https://serverfault.com/questions/239535/whats-the-ubuntus-default-shell/239537#239537)
Why are they configured differently?

According to the FAQ:
In FreeBSD's case, the reason is that
csh
is the only shell "guaranteed" to be on the base filesystem (stuff fromports
usually winds up in/usr/local/bin
, which defaults to a different filesystem). This is important because you don't ever want there to be a situation whereroot
can't log in because it's using a shell on a different (unmounted) filesystem.
