Chapter 38 ‘Using Emacs as a Server’ in ‘GNU Emacs Manual’ says [0] the
following:
You can run multiple Emacs servers on the same machine by giving
each one a unique “server name”, using the variable server-name. For
example, M-x set-variable RET server-name RET foo RET sets the
server name to ‘foo’.

First of all, ‘M-x set-variable RET server-name RET foo RET’ just does
not work, returning “Value ‘foo’ does not match type string of
server-name”. It actually should be ‘M-x set-variable RET server-name
RET "foo" RET’, since ‘server-name’ requires a string.
However, I found this example pretty confusing in general: when the
server is not started yet, setting ‘server-name’ with ‘M-x set-variable’
is impossible (variable does not exist yet); when the server is already
running, there is no much sense in setting it, since it does not rename
the instance on-the-fly.
¿Would not it be more useful to give as an example of how to start
multiple Emacs servers something like:
$ emacs --eval '(setq server-name "foo")' --daemon

Fixed on the release branch.

Fixed on master branch.

But it affects the next one.

I added this, but I don't think it should replace what's in the
manual: not all the uses of the server are in daemon sessions.
Thanks.
