Hello,

I am trying to use the new shepherd timers in my guix configuration.  I
got it working with some help on IRC, except I cannot figure out how to
configure the extra action.  Shepherd's manual gives this example:

--8<---------------cut here---------------start------------->8---
     (define updatedb
       (service
         '(updatedb)
         #:start (make-timer-constructor
                   ;; Fire at midnight and noon everyday.
                   (calendar-event #:hours '(0 12) #:minutes (0))
                   (command '("/usr/bin/updatedb"
                              "--prunepaths=/tmp")))
         #:stop (make-timer-destructor)
         #:actions (list timer-trigger-action)))
--8<---------------cut here---------------end--------------->8---

However I cannot figure out what to put into the (actions) field of the
shepherd-service record.  Documentation says it should be instance of
shepherd-action, however I have no idea how to turn the
timer-trigger-action into it.  Any suggestions?

Thanks,
Tomas
