I just want to say that I'm not ignoring the question--I honesty don't know. In any case, until we do know, I've applied your patch https://issues.guix.gnu.org/issue/45225#7 to guix master as commit b57056a9fd83c61efb5343853948a798da6e975e--after all, the font was in /boot for regular Guix Systems anyway, so I don't see a downside loading it from /boot--especially since it's part of the bootloader anyway, which does not have different generations for itself. Also, the code is simpler now. I also want to note that all 4 hunks in that patch had failed to apply with git am. I implore you to please download the patch files from https://issues.guix.gnu.org/issue/45225#7 using the little blue download arrow are the top right corner and try to "git am" them yourself. It won't work because the spaces in your patch files are mangled. If it's that way because git send-email doesn't work, I have a block like the following in ~/.gitconfig--and my patches arrive unmangled that way: [sendemail] from = Example User smtpEncryption = tls smtpServer = xxx smtpUser = xxx smtpPass = xxx smtpServerPort = 587 Then you can use git format-patch -1 -o ../outgoing-topic1 git send-email ../outgoing-topic1/0001* and it will work.
