[Warhammer 40k] What do units like Khorne Berserkers do in their downtime?

Champions of Khorne are always described as being eternally bloodthirsty, flying into a mad rage and slaughtering anything nearby if their bloodlust isn't satiated in time. I remember reading that devotees will incur Khorne's wrath if they go a day without bloodshed. But even Kharn has to travel in starships to get to the battlefield. What if it takes a week to get to a planet? What do Khorne Berserkers do when they are en route to a destination, etc? Surely they can't just go nuts and slaughter the crew of the ship they're on - it almost assuredly would mean their own demise as well. And their weapons and equipment would need maintenance eventually. They would eventually have to keep it together long enough to go on killing again.

They clean skulls and offer them for the skull throne. They fight each other or are kept locked up in chains so they dont... you know... kill everything by the time they get there. 

That being said there arent that many of them comparatively so as Ciaphus Cain observes in his memoirs, the Beserkers he does encounter almost overwhelmingly come from teleportation. The ones that dont arrive alongside warbands singularly. However the relative intactness of the warbandees/ers indicates that Khornate Beserkers have at least a modicum of self control.
