* 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
