Template: dash/sh Type: boolean Default: false _Description: Install dash as /bin/sh? Bash is the default /bin/sh on a Debian system. However, since our policy requires all shell scripts using /bin/sh to be POSIX compliant, any shell that conforms to POSIX can serve as /bin/sh. Since dash is POSIX compliant, it can be used as /bin/sh. You may wish to do this because dash is faster and smaller than bash.
