If you want to make a case for replacing ed(1), you're going to have
to come up with some concrete reasons for doing so, not just make a
(long and hyperbolic) statement that you don't like it.
Any Unix tool has to clearly fall either under the category of
non-interactive (grep, sed, ex) or interactive (vi, wget, sysinstall).
The case of non-interactive tools is simple : just do what you are told
on the commandline and exit. For interactive tools, at a minimum, the
application has to be show what data it is working on and what it does
with the data when the user presses a key (or a series of them). ed was
never meant to be non-interactive, and it does not fulfil the basic
requirements of being interactive. That's one reason. Secondly, how many
times does an average commandline user even think of using ed when he
needs to edit a file, even in the extreme case where there are no
alternatives ?
There have been some recent changes:
http://svn.freebsd.org/changeset/base/194628
<http://svn.freebsd.org/changeset/base/194628>
that suggest that this problem is being addressed.
Till the improvements are in place, we need the alternative of having vi
under /bin rather than /usr/bin.
Actually, it surprises me to what extent the core of the FreeBSD
community is enamoured with this idea of a micro-minimalistic base, in
which it is practically impossible to do anything except run fsck.
Matters don't stop there. Seeing the limitations of this approach, the
community churns up wierd workarounds like /rescue/vi, when all that was
needed was shift vi from /usr. You talk about the need for compliance
with old hardware and embedded systems to save a few kilos. How old is
the hardware that you have in mind ? The oldest system running FreeBSD I
know of is a 1997 Pentium with a 2 GB disk, and even that can easily
withstand the change I am suggesting. Machines older than that are
actually DEAD and don't have to be factored in. As for embedded systems,
the primary target of FreeBSD is servers, workstations and *tops. The
embedded world hasn't survived riding on FreeBSD, nor the other way
round. So from the viewpoint of the greatest good of the largest number,
over-indulging a mindset fixed around minimizing the base only leads to
degradation, not improvement. Getting to boast of a 900K / won't do any
good when people are thinking of having decent firepower (even while in
single-user mode) and its ease of use.
But I guess my words are of no use when the people who matter just won't
listen. So I give any hopes in this regard.
