Right.

Yeah, we can leave that for later.  :-)

Something’s wrong!

> * gnu/build/hurd-boot.scm (make-hurd-device-nodes): Do not create
> dev/{null,zero,full,random,urandom} mount points.
> (passive-translator-xattr?, passive-translator-installed?, translated?,
> set-hurd-device-translators): New procedures.
> (false-if-EEXIST): New macro.
> (boot-hurd-system): Use them instead of running MAKEDEV.

Nitpick: there shouldn’t be a bang here (just like for ‘mkdir’, etc.).

Otherwise LGTM, thank you!
