When running "guix-gc" without specifying any root, the complete content of 
/nix/store was classified as dead. This looks a bit excessive to me; should 
not at least the gnu build system that would be used to build a package 
with the currently installed guix be preserved? Even if the user has not 
installed gcc in his environement, for instance, the "current" gcc should 
be kept, whereas any older gcc (I had quite a few of them corresponding to 
several versions of guix) should be deleted.

If I see it correctly, this means that the output of
   guix-build hello --dry-run
should be kept in the store.


I also got the following error on the first run:

deleting `/nix/store/j29s9129di8lzx7xbc9rj0ywx05pivij-readline-6.2'
error: build failed: getting status of 
`/nix/store/j29s9129di8lzx7xbc9rj0ywx05pivij-readline-6.2': No such file or 
directory

But the next run worked and deleted everything.
