I use bash as my shell. However the depends for initrd and/or kernel-image want ash, so /bin/sh is ash. Maybe that should be changed to "POSIX_shell" or something, and have bash and ash provide POSIX_shell? | The main advantage of ash is that it's 1/5 the size of bash, though with | some limitations in functionality.

I know that ash doesn't handle color-code escapes like bash does. Apparently it does handle "export FOO='bar'", but /bin/sh on Solaris needs 2 separate lines for it. If ash uses readline then you should be able to get vi or emacs line editing to work by having one of set editing-mode vi # for vi set editing-mode emacs # for emacs in ~/.inputrc or /etc/inputrc. -D
