Setting link file permission in home-files-service-type

Setting link file permission in home-files-service-type

[c4droid]

Hi, Guix!

I'm changing my mailing workflow from fetchmail + procmail + msmtp +
mutt to fdm + msmtp + mutt, configuration file is already prepared, the
fdm and msmtp configuration file need 600 permission, guix home
home-files-service-type give 644 default, have workaround for when
symlinking change permission for target file.

My home.scm configuration cut:
``` scheme
(home-environment
 (services
  (list
   (service home-files-service-type
            `((".fdm.conf" ,(local-file "dotfiles/fdm.conf"))
              (".msmtprc" ,(local-file "dotfiles/msmtprc")))))))
```

I used msmtp for a while but discovered OpenSMTPd after switching to
Guix.  Never looked back. It's a lovely email program.

No pressure, but below is a config if you'd like to try it, too.

Kind regards
Felix

                      (config-file
                       (plain-file "opensmtpd-configuration"
                                   "

Hi, Felix
I'll take a look and try opensmtpd, if possible, I'll let opensmtpd
become a home service.

As mentioned on another thread recently, you need to pass the
`#:recursive? #t` option to `local-file` if you want to preserve your
file permissions.

``` scheme
(home-environment
 (services
  (list
   (service home-files-service-type
            `((".fdm.conf" ,(local-file "dotfiles/fdm.conf" #:recursive? #t))
              (".msmtprc" ,(local-file "dotfiles/msmtprc" #:recursive? #t)))))))
```

Happy hacking!
  Gary
