Hi Guix,
As discussed on IRC with LudoοΏ½ and Ricardo,
4252dace19945f56192477e8cb07973c20a526ba introduced a circular dependency
among gnu/services modules, by adding a dependency between from base ->
admin, resulting in the full dependency chain:
mcron -> base -> admin -> mcron
I ran into this when building a channel. The error reported by guix pull
was:
```
(repl-version 0 0)
(exception misc-error (value #f) (value "Unbound variable: ~s") (value (mcron-service-type)) (value #f))
```
LudoοΏ½ determined the full error was:
```
gnu/services/admin.scm:161:21: Unbound variable: mcron-service-type
```
by running the repl directly:
```
echo '(primitive-load "/gnu/store/vf892np8mnh2zx9dppcv9k25xk648n2d-inferior-script.scm")' \
| "/gnu/store/j7vxgnaqwimrzsnd8zhq9x1jdp7afl0s-guix-ca45da9fc/bin/guix" "repl"
```
Options for solving this problem include moving the guix-publish service
into another module. However, this would break the API of (gnu service base),
so we should be careful when doing that.
It doesn't look like guix-publish is used elsewhere in the Guix code
proper currently.
For now, we might want to revert 4252dace19945f56192477e8cb07973c20a526ba.
Best,
Jack
