Guix, Installing guix from source fails on the build of openssl@1.1.1l. I see the same error on my working system (log attached) when executing the command below. The issue looks to be caused by OpenSSL's expired test certs fixed in 1.1.1p [0]. Guix currently grafts openssl 1.1.1s but it seems grafts are not part of the bootstrap process (substitutes disabled). If this is the correct diagnosis then we should be ungrafting before future releases any bootstrap dependencies relating to build failures (not necessarily for security updates). My personal fix was to adapt my installation script to iteratively set back then reset the clock, as openssl only builds in the past but diffutils-boot0 then fails due to newly created files being older than distributed files.
