“Can you really speak of a program being free software if you cannot bootstrap it?”, says our guest Janneke. He is the founder of GNU Mes, a project addressing the security concerns that arise from bootstrapping an operating system using large, unauditable binary blobs.
GNU Mes helped to reduce the number and size of binary seeds that were used in the bootstrap of GNU Guix 1.0 by a factor ten from ~250 to ~25 MiB.
Janneke talks about working on GNU Mes, its community, NGI Zero funding and calls for a fifth freedom: Freedom Four. The freedom to build a program totally from source.
