This is fixed in the Shepherd 0.9.3, which landed in Guix commit
283d7318c5b312d7129adb6dbeea6ad205ce89d1.

As I wrote, I’m not sure whether it fixes the nginx situation since I
could not reproduce it.  I’m closing and let’s open a new issue
specifically for nginx if it comes up again with 0.9.3.

Thanks,
Ludo’.
