* gnu/packages/commencement.scm (%bootstrap-guile+guild): Make public.
[properties]: New field.
* gnu/system/bootstrap.scm (hash-script): New procedure.
(bootstrapping-os): Wrap OBJ in 'hash-script'.
This allows us to perform arbitrary builds on a system that has no
userland besides the build process itself, running as PID 1.
Suggested by Vagrant Cascadian.
DRAFT: The resulting system does build things, but this is all happening
into memory, which may or may not be a problem (it allows us to not have
disk drivers in the kernel!). More importantly, it does not display
anything upon completion, and the build result is lost as well.
* gnu/system/bootstrap.scm: New file.
* gnu/local.mk (GNU_SYSTEM_MODULES): Add it.
