Hi rennes!

Woohoo!  Does that mean you were able to run packages cross-compiled
with Guix, or packages built natively with Guix?

… or did you build a VM image of GNU/Hurd?

Things like ‘guix system vm’ use QEMU because we need to start a VM
because on GNU/Linux one needs to be root to create a file system, mount
it, and populate it.

However, on GNU/Hurd, file systems can be mounted without being root.
So you could in fact skip QEMU altogether, though that’d require
tweaking in the VM-generation code (in (gnu build vm), etc.).

We could probably get rid the lsof dependency.  What matters here is a
Linuxish /proc.

Anyway, congrats on this milestone!  :-)
