Hi Guix,
As discussed on IRC with Ludo’ 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))
```
Ludo’ 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

This is fixed (surprisingly easily!) by commit

Let me know if you notice anything wrong!
Thanks for the bug report,
Ludo’.
