Hi!

Changes since v1:

  • Add ‘delete-duplicates’ call in ‘references-file’.

  • Work around unreliable signal delivery in Guile (note that
    this is not a new problem; I just happened to notice it).
    This part is unsatisfactory.  The solution in the Shepherd is
    signalfd(2) on GNU/Linux, but using it requires quite a bit
    of infrastructure.

  • New #:child-is-pid1? parameter for ‘call-with-container’, set
    to #false by ‘least-authority-wrapper’.  This is probably
    overkill for most cases (daemons that, unlike Jenkins, don’t
    run arbitrary user scripts are unlikely to leave zombies
    behind them), but safer.

  • Converted opendht service to ‘least-authority-wrapper’.

I think it’s good to go.

Thoughts?

Thanks,
Ludo’.
