It is a user process run in a user session, so it is not something the package 
maintainers should touch.

But akonadictl stop  for all users in question would do it. Then remember 
which users you did it for, and akonadictl start afterwards for those users 

But I would expect that to end up as a severe policy violation; I don't have a 
reference handy though.

Also be aware that the users mail client, calendar app and similar will be 
greyed out and text on top : "Akonadi  not running" and then a giant button in 
the middle that says "start akonadi" tempting users to press it. And it does 
what it says on the tin.
