Re: lightdm updates need to review.

[jbranso@dismail.de]

Thanks for the submission Feng!

Just a couple of things:

1) Try to send your email as plaintext, not html.  Most developers prefer 
plaintext emails.  :)

2)  I would encourage you to read this webpage: 
    https://guix.gnu.org/manual/devel/en/html_node/Submitting-Patches.html

   Essentially you should submit patches with "git send-email"
   ( https://git-send-email.io/ ), and you should submit patches to:
   guix-patches@gnu.org .  Guix devel does not create an bug report.
   BUT guix-patches@gnu.org will create a correspending bug report at
   issues.guix.gnu.org.

Thanks again for helping guix!
