Hi,

I'll close it because it seems the main concern should have been fixed
with c9d92409d4d3f587f73c6f48f845a913f7278ad1, but please comment/reopen
if you still reproduce an issue.

Thanks,

A few things are not working with the Guix rsync service:

1. A "files" module is created by default:

--8<---------------cut here---------------start------------->8---
# Generated by 'rsync-service'.

pid file = /var/run/rsyncd/rsyncd.pid
lock file = /var/run/rsyncd/rsyncd.lock
log file = /var/log/rsyncd.log
port = 873
use chroot = true
uid = rsyncd
gid = rsyncd

[files]
path = /srv/rsyncd
comment = Rsync share
read only = false
timeout = 300
--8<---------------cut here---------------end--------------->8---

But rsync-configuration does not allow the user to specify another
module name, nor to add a module.  This is limiting.

Furthermore, the default module name is not documented, so one has to
guess that the client must invoke

--8<---------------cut here---------------start------------->8---
rsync ... $HOST/files ... # The "files" here matters!
--8<---------------cut here---------------end--------------->8---

2. The `uid' option does not work.  With the following configuration

--8<---------------cut here---------------start------------->8---
(service rsync-service-type
            (rsync-configuration
             (uid "ambrevar")
             (gid "users")
             (share-path "/whatever")
             (read-only? #t)))
--8<---------------cut here---------------end--------------->8---

I get this on guix reconfigure:

--8<---------------cut here---------------start------------->8---
building /gnu/store/lvkplmcxr785x56022hm8d88x0fbpd0m-switch-to-system.scm.drv...

Cheers!
