2020-12-07services: hurd-vm: Avoid circular dependency with (gnu system images hurd)....* gnu/services/virtualization.scm (hurd-vm-disk-image): Use 'lookup-image-type-by-name' instead of referring to 'hurd-disk-image' from (gnu system images hurd). Ludovic Courtès
2020-10-25services: guix: Make /etc/guix/acl really declarative by default....Fixes <https://bugs.gnu.org/39819>. Reported by Maxim Cournoyer <maxim.cournoyer@gmail.com>. * gnu/services/base.scm (substitute-key-authorization): Symlink DEFAULT-ACL to /etc/guix/acl unconditionally. Add code to optionally back up /etc/guix/acl if it was possibly modified by hand. * doc/guix.texi (Base Services): Clarify the effect of setting 'authorize-keys?' to true. Mention the backup. Give an example showing how to authorize substitutes from another server. Ludovic Courtès

2020-09-29services: secret-service: Add initial client/server handshake....This allows the client running on the host to know when it's actually connect to the server running in the guest.

Read from SOCK an initial message from the server. Return #f on error. (secret-service-receive-secrets): Send 'secret-service-server' message to the client.
