* gnu/services/tor.scm (tor-shepherd-service): Run ulimit -n before
launching Tor.
---

Guix,

I got a kind mail from an authorised Torperson[0] that one of my nodes was running low on efdees.  Sure enough, it was the Guix one.

This patch does the job, but boy, would I like to know if there's a better way to do it.

Kind regards,

T G-R

[0]: Yes, I did bite their official-looking badge to make sure it wasn't just someone trying to ingratiate themselves with incompetent relay operators.

Instead of going through Bash, what about something like:

  (lambda _
    (let ((pid (fork+exec-command/container …)))
      (container-excursion* pid
                            (lambda () (setrlimit 'nofile 32768 32768)))
      pid))

?
