Thank you for the explanations. Cool!

Awesome if upstream are responsive.

I have seen that 1.4-rc1 is just released. Hope that everything about
reproducibility will be fixed. ;-)


I have not yet tried your patches. Sorry bit busy at work.
And I will not have any slot next week, so I will be back on the topic
after the Guix Days. Except if someone beats me. :-)
(see you there :-)


Thank you for improving the Julia ecosystem in Guix because Julia is
becoming quite popular.

Cheers,
simon
