please use git-version, likes: 

(define-public lightdm-mini-greeter
  (let ((commit "ead7936993b4e9e067d73fa49dec7edfb46c73a8")
        (revision "0"))
   (package
      ...
      (source
         (origin
           (method git-fetch)
           (uri (git-reference
                   (url "https://github.com/prikhi/lightdm-mini-greeter")
                   (commit commit)))
           (file-name (git-file-name name version))
           (sha256
            (base32
             "17iy1jkllmi2xc95csb18wcfvbk44gyva2in2k5f29fy362ppz25"))))
      ...)))
   
and add comment for why use commit, not git tag.
