All good points!  Most of these are now fixed on the Shepherd side:

  48e53a4 guix: Record the right Fibers .go file directory.
  98878a7 system-log: Serialize information about sockets and the kernel log file.
  be57f65 system-log: Close input file on end-of-file.
  21bd4ec system-log: Print “localhost” for messages received over AF_UNIX sockets.
  1ad90aa system-log: Read kernel messages from /dev/klog on the Hurd.

Regarding cross-compilation, here’s a protip:

  guix build -L $PWD/.guix/modules shepherd <at> 1.0.99-tarball \
     --target=i586-pc-gnu

It works because it first builds the tarball, which includes
pre-generated man pages, and then uses it as the source of the Shepherd
being cross-compiled.

Thanks a lot for the detailed bug reports and suggestions; it’s much
appreciated!

Ludo’.
