Well, from (gnu packages linux)
--8<---------------cut here---------------start------------->8---
(origin
(method computed-origin-method)
(file-name (string-append "linux-libre-" version "-guix.tar.xz"))
(sha256 #f)
--8<---------------cut here---------------end--------------->8---
and from (gnu packages gnuzilla)
--8<---------------cut here---------------start------------->8---
(origin
(method computed-origin-method)
(file-name (string-append "icecat-" %icecat-version ".tar.xz"))
(sha256 #f)
--8<---------------cut here---------------end--------------->8---
but not from Chromium, if I read correctly.
From my understanding, we could have something like,
(sha256 (no-hash))
where ’no-hash’ would return a string, say
"0000000000000000000000000000000000000000000000000000" or whatever else
that would satisfy this hypothetical ’sha256’ sanitizer.
Cheers,
simon
