"dash" is a POSIX compliant shell that is much smaller than "bash".
We take advantage of that by making it the shell on the installation
root floppy, where space is at a premium.
.
It can be usefully installed as /bin/sh (because it executes scripts
somewhat faster than "bash"), or as the default shell either of root
or of a second user with a userid of 0 (because it depends on fewer
libraries, and is therefore less likely to be affected by an upgrade
problem or a disk failure). It is also useful for checking that a
script uses only POSIX syntax.
.
"bash" is a better shell for most users, since it has some nice
features absent from "dash", and is a required part of the system.
