The problem is that enabling the libedit support does not provide you
with auto-completion, AFAIK. This makes it very painful for a use
as a daily interactive shell, isn't it?

Plus, regarding the documentation, all the shells around claim to
comply with POSIX, so you can stick with the dash man page and use
another shell, it will work 90% of the time. You can also directly
refer to the standard:

In fact, dash uses two files: .profile, when you use it as a login
shell, and the file pointed in the ENV environment variable, used in
all invokations as interactive shell. So, it is the same scheme as
bash with .bash_profile and .bashrc.

Seb.

P-S. I would also like to use dash as my main shell (not just to
test script portability). I currently use mksh, which seemed to me a
good compromise: smaller and faster than bash, reasonnable
auto-completion support, path facilities (e.g. "ls -d /{e,b}*"), a
good support for UTF-8, and the ability to deal with many
bashisms/kornisms when you really need it:

You can also glance the ash in Busybox, which also provides
auto-completion, and is a fork of dash. Just build the ash applet to
get a ~80K shell:
