Hello Guix,
Since commit 8cb1a49a3998c39f315a4199b7d4a121a6d66449, the
define-configuration machinery in (gnu services configuration) uses
*unspecified* instead of 'disabled for an unspecified field value.
While this is indeed an improvement in readability, it introduces an
extra complication: because this new value is not self-quoting, it
cannot be used as is in G-Exps, and values using it must be carefully
expanded outside the gexp context, which is error prone.
This broke the jami-service-type, when partially specifying a
jami-account like so:
--8<---------------cut here---------------start------------->8---
(service jami-service-type
(jami-configuration
(accounts
(list (jami-account
(archive "/etc/jami/some-jami-account.gz"))))))
--8<---------------cut here---------------end--------------->8---
When building the operating system containing the above fragment, the
following error is throw:
--8<---------------cut here---------------start------------->8---
guix system: error: #<unspecified>: invalid G-expression input
--8<---------------cut here---------------end--------------->8---
The following change to the jami-provisioning test can also reproduce
the problem:

I'd suggest we revisit 8cb1a49a3998c39f315a4199b7d4a121a6d66449 to use
'unspecified (the symbol) instead of *unspecified*, which *can* be
serialized without any fuss in gexps.
Thoughts?
Thanks,
Maxim
