Minimum requirements for building everything on GuixSD?

[swedebugia]

Hi

During my now ongoing compilation of ALL packages on an x86 machine* I 
ran into a couple of issues:

1) 2 builds ran out of memory (qt 5.5.1 and webgtk)
2) diskspace consumption is larger than I expected
3) It takes weeks to complete it seems (after 8 days so far <50% done)

*I have P4 2 core 3,2GHz, 1GB ram, 1GB swap and 40GB partition

I heard from fps (after partitioning) that his x86_64 builds size about 
70GB in total.

cheers
